Chevy Malibu clunking noise?

Bad Sway Bar Link: A vehicle’s sway bar or anti-roll bar, helps reduce body roll while cornering. If the sway bar breaks or is damaged it may produce a clunking or knocking sound, especially when going over bumps. Your vehicle may also had more difficulty handling when the sway bar is damaged.

  • If you own a 2008-12 Chevrolet Malibu and experience a Chevy Malibu clunking noise, or pop, snap, creak when braking, turning or driving on uneven surfaces, this may be the fix for you. Shops report that the engine cradle mounting washers may be contacting the frame rail.

What does clunking noise mean?

If a ball joint is beginning to fail, you may notice a clunking noise coming from the front wheels. When a tie rod end is worn or loose, they may produce a clunking noise. Worn tie rod ends may also cause more play in the steering wheel, making turning more vague.

Why do I hear clunking when I drive?

This symptom typically happens when you have a suspension issue, and occurs when driving over bumps, uneven surfaces, debris, potholes, and more. It could be that some suspension part is loose or broken. The suspension system is fairly complex, so finding the exact source of the noise can be tricky to do by yourself.

How is a clunking noise diagnosed?

To test it for any movement, such as popping in and out, with your hands at 3 and 9, shake your tire from side to side. If it’s popping in and out, that could be causing a clunking noise. You can also inspect your power steering rack for movement and coinciding noise as well by shaking your wheel from left to right.

Does a Chevy Malibu have a cabin filter?

There are two main air filters in your Chevy Malibu. The cabin air filter is located either behind the glove compartment, under the dashboard, or under the hood of your vehicle.

Is it safe to drive with clunking suspension?

It is not recommended. A damaged or collapsed spring can cause sagging and noise and affect alignment angles. While you can still drive, the ride will be rough and the car will be difficult to control in an emergency. Plus, bumps could damage other parts of the car.

Why is the back of my car clunking?

Clunking noises that happen when you drive your car over bumps could be from the following: Worn or damaged struts. Worn or damaged leaf spring shackles. Worn or damaged control arms.

Can shocks make a clunking noise?

There is most likely nothing wrong with the replacement shock or strut, but a metallic clunking noise typically indicates loose or worn mounting hardware. A loose mount can allow movement between the bolt and attaching parts, while a mount that is worn can cause the shock/strut to move up and down.

Do bad struts make a clunking noise?

Some worn-out struts (but not all) will make noises that can alert you to their declining state. Bad strut sounds are usually described as a hollow clunking or banging type of sound. It’s also possible to get a bad strut mount sound—an audible clunking or creaking when turning the steering wheel.

What can causes a clunking sound in front end when turning?

Tie Rods: A clunking noise when turning could indicate a loose or broken tie rod. Sway Bar Link: With a failing sway bar link, you will not only notice a knocking noise while you are turning but poor handling as well.

Can a bad wheel bearing cause a clunking sound?

Knocking/Clunking Noise While Turning When a wheel hub bearing wears out, it puts extra stress on the CV-joint. That can cause the knocking/clunking noise when you turn the vehicle.

Can bad tie rods cause clunking noise?

When your tie rods go bad, the symptom you’re most likely to experience first is a vibration or shaking sensation in your steering wheel. You may also hear associated clunking and rattling noises, especially when turning the vehicle at low speeds. These sounds are caused by tie rods that are starting to wear out.

How often should you change cabin air filter?

Cabin Air Filters should be changed about every 30,000 miles. But, it’s always best to consult your owner’s manual for your recommended vehicle maintenance needs to have your air filter changed.

What Does the Check Engine Light Mean?

Please wait for the page to load completely before continuing.

Will the check engine light reset itself?

When the problem or code that caused the check engine light to illuminate is resolved, the check engine light on your Chevy Malibu will generally turn off by itself. For example, if a loose gas cap was the reason of your check engine light going on, once the cap is tightened, the light will turn off by itself within a few minutes. Similarly, if your catalytic converter is failing and you’ve been doing a lot of stop-and-go driving, the check engine light may have come on as a result of the large amount of time the converter has been put through its paces.

If you exceed that limit and the light remains illuminated, you will need to bring your vehicle into Hare Chevrolet so that the light and code may be examined and reset.

Is it safe to drive your Chevy Malibu with the check engine light on?

Because everything is dependent on the severity of the problem, this is a difficult question to answer without a lot of thought. If the problem is a small one, such as a loose gas cap, it should be possible to commute without interruption. A constant glow of the check engine light is usually seen as an indication of this. The performance of your car may have changed, which might be an indicator of a more serious problem with the vehicle. If your Chevrolet Malibu’s check engine light is on and flashing, this indicates that there is a serious problem with the vehicle, and it is suggested that you have it serviced as soon as possible.

Alternatively, slow down and transfer your Chevrolet to one of our qualified experts as soon as it is operational.

Check Engine Light Service Chevy Malibu

You’re traveling down the road in your Chevy Malibu when suddenly a yellow light appears on your dashboard, indicating that you should ‘Check Engine’ your vehicle. Your heart falls a little, if you’re like the majority of Chevy owners, since you have no idea what that light is trying to tell you or how you should respond. Stress can be exacerbated by apprehension about the unknown (or the potential expense of the unknown). It’s important to remember to take a deep breath and understand that the light on your Chevy Malibu does not always mean you have to pull over to the side of the road and contact a tow truck, but it is advised that you have your car examined as soon as possible.

When the ECM (electronic control module), which is the vehicle’s onboard computer, detects a fault in the electronic control system that it is unable to rectify, a computer activates the check engine light on your Chevrolet Malibu.

This code is scanned by our Chevy vehicle repair experts at Hare Chevrolet using an electronic scan instrument, which they use to diagnose the problem.

While this code will inform you of the problem that has been found, a true diagnostic will still need the services of a qualified expert to establish the problem and correct it.

How much does it cost to get the engine light checked?

The check engine light can indicate a variety of problems ranging from a loose gas cap to a more serious failure such as a broken catalytic converter or a problem with one of the car’s oxygen sensors, so it’s important to acquire a clear code reading and diagnostic as soon as possible. The average cost of a check engine light diagnostic and testing is typically between $88 and $111, depending on the location. The good news is that Hare Chevrolet provides comprehensive multi-point checks as well as free diagnostics in the majority of situations to assist you in determining the source of your check engine light.

Chevy Malibu Check Engine Light Codes

When the check engine light shines on your vehicle’s dashboard, it may be rather frightening to see that small light suddenly illuminate, but in truth, it is not anything that should drive you to shut down in panic right immediately. If you hear the phrase diagnostic trouble codes (DTC), this is simply another name for the codes that appear on your dashboard when your engine is running. Essentially, these are automotive computer codes that are kept by your Malibu’s ECM, commonly known as the OBD (on-board computer diagnostic system).

The fact is that, while it may seem intimidating at first, learning how to do simple diagnostics can provide you with valuable information about your car as well as allow the Check Engine Light to do what it was intended to do: serve as a guide.

Because there are hundreds of different OBD codes, there are also hundreds of conceivable causes for the indicator to be illuminated, including the following:

  • Trouble with the transmission
  • Trouble with the emissions controls
  • Trouble with the computer output circuit
  • Trouble with the ignition system a faulty battery
  • Faulty spark plugs Gas cap that has come undone or that has gone missing
  • Sensor for oxygen
  • Problems with the fuel and air metering systems

Trouble with the transmission; trouble with the emission controls; trouble with the computer output circuit; trouble with the ignition system Batteries that are too old or have worn out spark plugs Gas cap that is either loose or not present. Sensor for measuring oxygen levels. System failures in the metering of fuel and air.

Transmission problems; Emissions-control problems; Computer-output circuit problems; Ignition-system problems a faulty battery; faulty spark plugs; Gas cap that is either loose or missing; Sensor for measuring oxygen levels; Fuel and air metering system malfunctions;

How many miles can you drive with the check engine light?

Because each check engine code has a different level of severity, it is difficult to forecast how many miles you will be allowed to drive with the warning light illuminated on your dashboard. If your check engine light is illuminated, we recommend that you pull over and contact Hare Chevrolet for assistance in determining if your vehicle is safe to drive or whether a tow truck is required. Attempting to comprehend the code and then planning your strategy effectively is the best bet. It might be anything from a faulty sensor to faulty plug wires that require replacement.

What could cause the check engine light to come on in a Chevy Malibu?

Your gas cap might be loose or need to be replaced if your check engine light turns on. If this is the case, tightening or replacing your gas cap could solve the problem. On the other hand, your vehicle’s check engine light might also be an indication of a significant malfunction that could cause serious damage to your engine and result in a large repair expense. The check engine light will either glow or blink depending on your vehicle’s make and model. A constant glow normally signals something less serious, however a flashing check engine light indicates that your vehicle’s engine is in significant condition and that quick assistance is required to fix the problem.

If your Chevrolet Malibu’s check engine light is up, we strongly advise you not to drive the car and to book Chevy servicing as soon as possible. The following is a list of the most typical reasons why your check engine light may illuminate:

  • Your gas cap might be loose or need to be replaced if your check engine light turns on. If this is the case, tightening or replacing your gas cap could resolve the problem. Furthermore, the check engine light might be a warning sign of a major problem that could cause catastrophic damage to your engine and result in a significant repair price. The check engine light will either glow or blink depending on the make and model of your vehicle. Typically, a continuous glow suggests something less serious, but a flashing check engine light signals that your vehicle’s engine is experiencing major problems and that emergency assistance is required. It is highly recommended that you do not drive your Chevy Malibu if the check engine light is on and that you book Chevy servicing immediately. Listed below is a list of the most typical causes of your check engine light to illuminate:

Chevy Malibu Check Engine Light Flashing

We know from years of offering Check Engine Light Diagnosis Service that there are several typical explanations for an illuminated Check Engine Light, including something as simple as a loose gas cap, despite the fact that there are several probable causes. In addition to malfunctioning fuel injection systems, unclean mass airflow sensors, bad emissions control parts, broken oxygen sensors, faulty head gaskets, and defective spark plugs are also major causes of the Check Engine Light. The Chevy Certified Technicians and certified service routine are on hand to identify the source of the problem and fix it as necessary to restore factory standards, no matter what caused the Check Engine Light to illuminate.

Every Chevy Malibu is equipped with a high-tech performance monitoring system that includes a computer and a set of sensors that are strategically placed throughout the car on its critical systems to provide real-time data.

If the electronic control unit determines that the data is not in accordance with manufacturer requirements, the Check Engine Light will light, alerting you to the fact that there is an issue.

Our Check Engine Light Diagnosis Service isolates the root cause of the problem and offers you with an advice on what to do next from a Highly Qualified Service specialist, which is where Hare Chevrolet comes in.

Diagnosing Steering System Noises

All kinds of steering system sounds, including squeaking, whining, grinding, and popping are heard! It might be difficult to determine the source of unusual noises that occur as a result of steering system operation. In this article, we will discuss a variety of potential noise sources, including the steering column, power steering pump, steering linkage, and other associated components, all of which can contribute to the formation of undesired and uncomfortable noises in the vehicle. It is most typical that low power steering fluid levels are the root cause of power steering noise.

  • It is most often the result of a worn or incorrectly fitted power steering drive belt that produces a high-pitched or ‘screeching’ noise.
  • This is frequently mistaken as a problem with the steering system.
  • In the ‘good old days,’ ATF was commonly utilized in power steering pump systems, and this was not uncommon.
  • Using the incorrect type of fluid can result in a variety of issues ranging from aeration to pump seal damage.
  • When in doubt, always refer to the service or owner’s handbook to determine the proper type of fluid to use.
  • The fluids suggested by various vehicle manufacturers are included in this section as a guideline.
  • In accordance with the year, BMW – Pentosin CHF 7.1 or CHF 11S Chrysler-P/S fluid (used before to 1998), ATF+4 (used after 1998), or Pentosin CHF 11SD (used after 1998) Is it the aewoo-Dexron II or III?
  • Honda-Honda Power Steering fluid Hyundai-P/S fluid 3 or Dexron II are two options.

Jeep-WK hydraulic fluid, ATF+4 fluid, or P/S fluid are all options (depending on model) Infiniti-Dexron III is a fusion of the words ‘infinite’ and ‘dexron.’ II or III-generation Isuzu Dexron Kia -P/S fluid or Dexron III are two options (depending on model) Deltron II or III, a Land Rover product.

  1. Pentosin CHF 11S or P/S fluid for Mercedes-Benz vehicles Mini-Pentosin CHF 11SM (Mini-Pentosin) Itsubishi-P/S fluid, also known as Dexron IINissan, was introduced in 1994 and afterwards.
  2. issan/Datsun-Pre-1994.
  3. Porsche-Pentosin CHF 11S (or CHF 202 if you like).
  4. Scion-Dexron II or III is a kind of dexron.
  5. Suzuki-Dexron II or III is a kind of Suzuki-Dexron.
  6. Pentosin CHF 11S, Pentosin CHF 202, Volkswagen-P/S fluid, Pentosin CHF 11S (varies by year) Pentosin 7.1 CHF, 11S CHF, 202 CHF Volvo-Pentosin (varies by year) NOTE: While Pentosin 7.1 is derived from minerals, Pentosin CHF 202 and CHF 11S are derived from synthetic materials.
  7. The system should be flushed once the incorrect fluid has been supplied, and the system should be bled (‘burped’) to remove any remaining air.

hoses for the power steering When replacing power steering hard lines, keep in mind that some bargain-brand lines may be constructed with a thinner wall than OEM lines, resulting in harmonics being passed through the lines and resulting in a whine or high-pitched sound.

If the hoses come into touch with the body, frame, or engine, it is quite likely that a ‘mystery’ noise will be heard.

Damaged with pinholes or loose, brittle, fractured, or cracked with pinholes, for example, may be the result of an insufficiently sealed power steering return line, which may be enabling air to enter the system and cause foaming and noise to be heard.

(See illustration.) Air pressure of no more than 8 psi should be used to gently pressurize the power steering pump reservoir, and the return pipe should be checked for leaks.

If a client complains of a noise when moving the steering wheel right or left, the brake calipers and caliper brackets should be checked for damage.

CV joints are a type of joint that has a curved surface.

It is possible that if the condition is neglected, the CV joint will fail completely, resulting in a no-drive scenario.

If a client complains of a humming, rumbling, or growling sounds that gets louder as the steering wheel is cranked, the front hubs may be to blame for the problem.

Problems with the power steering pump If the power steering pump is loud and there is no power steering aid, it is likely that air has become trapped in the system.

If the fluid looks to be burned or tainted, the system should be flushed.

Slowly spin the steering wheel to full lock in one direction while the car is elevated off the ground and the engine is turned off.

Then, carefully spin the wheel to full lock in the other way and wait five seconds before doing it again.

Continue until the fluid seems normal and there is no evidence of foaming.

If there is a whining or moaning sounds coming from the pump, air is present in the system.

Fill the pump reservoir with water and place the rubber stopper from the vacuum tool into the reservoir fill neck.

For approximately five minutes, rotate the steering wheel from full lock to full lock every 30 seconds.

Turn off the engine, release the suction, and then remove the vacuum tool.

Restart the engine and turn the steering wheel a few times, paying close attention for any leaks at any of the hose/line connections.

Misdiagnosis of the pump If you hear a noise, don’t instantly assume that it’s the power steering pump making it!

The Chevrolet and GMC pickup trucks and Oldsmobile Bravada cars with 4.3L, 5.0L, and 5.7L engines from 1992 to 1993 are examples of what Cardone is talking about.



Start the engine (without driving the car) and listen for any unusual noises.

If the noise persists, it is necessary to analyze the remaining driving components, which includes the alternator, as well.

After the defective component has been replaced, attach the proper driving belt and check that the repair was successful.

The manual rack and pinion is included in the EPS system (electronic power steering system).

Unlike a hydraulic system, the various torque characteristics of this system are not typical of that type of system.

Failure to adhere to this criteria may result in a noise that is not correctly identified.

of torque must be applied to the rack mounting bolts, plus an extra 90 degrees of rotation (torque-plus-angle method).

Additionally, air in the power steering system might result in the same problem.

When spinning the wheels at a slow pace, there is a grunting or shuddering in the steering.

When the steering wheel is moved to the stop position, a moaning or humming sound is heard from the power steering pump.

When driving over a bump, there is a clunk noise from the steering gear.

When twisting the steering wheel from lock to lock, there is a screech or chirping from the belt.

PROBLEMPOWER steering hiss or whistling noise is present.

Ensure that the steering column bracket is not grounded or that it is not loose.

In addition, a loud valve in the power steering gear might be the source of the problem.

CAUSE Check for loosened column brackets and fasteners, worn, loose, or dry column bearings, worn or damaged steering shaft insulators, or a compressed or stretched steering column shaft/coupling by removing the steering column and inspecting it.

A squeak or rubbing sounds may be heard in certain conditions CAUSE The vehicle’s power steering fluid was the incorrect type for it (for example, using ATF instead of power steering fluid).

Another potential source of trouble is a twisted or incorrectly positioned steering shaft stone shield.

CONDITIONSqueaking and grinding in the steering column.

When the fluid temperature is below 130 degrees Fahrenheit, the power steering pump relief is noisy.

Condition that is considered normal.

CAUSE: Low amount of power steering fluid, aerated power steering fluid.

Pump for the power steering has failed.

An air leak between the fluid reservoir and the pump might possibly be the source of the problem.

CAUSE Gear contact with surrounding components, and worn steering gear internal stops are all possible.

Chevy Malibu: Engine Knock → Causes & Diagnosis

The engine banging in your Chevrolet Malibu is one of the most frightening noises you might hear emanating from your vehicle. When an engine knocks, it might be an indication of more serious engine issues. It is typically caused by a variety of factors such as ignition problems, timing problems, worn lower engine components, and more. We’ll go over the most prevalent reasons behind this in more detail below. By definition, an engine knock is created by the combustion of the air/fuel combination at the incorrect moment or by the combustion of the mixture in an inconsistent manner.

As opposed to having a single continuous fire, the first clump will burn the next clump and so on.

When an exhaust leak is originating from one of the manifolds, it may frequently be heard as a knocking sound.

Engine Knock Causes:Chevy Malibu

Is the check engine light illuminated before you begin your investigation? If this is the case, it is time to retrieve the diagnostic codes from the ECM and utilize them to assist you in identifying the problem. The local parts store will normally scan for codes for you as a favor if you don’t have an OBDII scanner handy. Some of the most prevalent faults that might cause your Malibu’s engine to knock are as follows:

Bad Spark Plugs

Damaged spark plugs are the most typical cause of an engine that is banging on the ground. Spark plugs are critical to the correct operation of an engine. An very powerful spark is required for a powerful and clean combustion to take place. Spark plugs can fail for a variety of causes over time, including the following:

  • Wrong Plug – If you aren’t using the spark plug advised by Chevrolet, it would be a good idea to change them out for the correct plug. The incorrect plug can burn too hot or too cold, which has a direct influence on the combustion process and can cause engine banging, among other problems. Spark plugs can become worn over time. You should replace your spark plugs at the specified intervals. If you have a lot of miles on your vehicle or if the plugs appear to be worn, you should replace them all.
See also:  P0172 System too Rich

Spark plugs are the most frequent component of the ignition system that might cause your Malibu to knock, and they are the first place you should investigate if your vehicle is clunky. However, there are additional components, such as the coil packs and plug wires (if applicable), that you should examine. The coil pack is responsible for delivering a spark to the plugs. However excellent the spark plugs may be, if they are sending a weak spark, the air/fuel mixture will be unable to ignite correctly, regardless of how good the spark plugs are.

Carbon Deposits

Carbon can accumulate at the top of the combustion chamber of your Malibu. The compression ratio is effectively increased as a result of this. Detonation can occur if there is too much compression. Modern fuels must be able to maintain carbon cleaning detergents mixed in with them in order to function properly. Despite this, deposits continue to accumulate, which might result in a banging sound. This means that you will have to take your Malibu to a shop to get it cleaned. You may also use one of those cleaners in a bottle, but we urge that you bring it to a specialist for assistance.

Wrong Octane/Bad Gas

Engine knocking might be caused by contaminated gasoline in your Malibu.

A banging sound might also be caused by using the incorrect gasoline. It is critical to use gasoline with the appropriate octane rating. If you really must use premium fuel, then do so. Saving a couple of dollars every fill-up might have serious consequences for the health of your engine.

Air/Fuel Mixture Too Lean

Leaning out the air/fuel mixture might be caused by sensor malfunctions. When the mixture becomes extremely lean, it has the potential to cause your Malibu’s engine to bang. A lean air/fuel mixture can be caused by faulty fuel injectors, oxygen sensors, MAF sensors, and other components.


Several internal components of your Chevy Malibu’s engine, including the sensors and computer, work together to synchronize engine timing so that the spark plug ignites at precisely the appropriate time. The gasoline will ignite at an incorrect moment if there is an error in this timing. This will result in an unpleasant knocking sound. See also: Symptoms and Diagnosis of Timing Chain Jumped Symptoms of a Bad Timing Belt or Chain in a Chevrolet Malibu

Knock Sensor

Modern engines are equipped with a knock sensor, which automatically corrects knocking. When the knock sensor malfunctions, the engine might start to knock. In many cases, a faulty knock sensor will provide a problem code, such as P0325(knock sensor ‘1’).

Worn Bearings

Rod bearings are found between the crankshaft and the piston rods of the engine. If the pistons become worn out, they will no longer be able to operate smoothly. When this occurs, your Malibu will make a knocking sound. In this case, the only thing that can be done is a lower engine rebuild.

Conclusion:Malibu Engine Knock

Alignment & Suspension Specs: 2004-2007 Chevrolet Malibu

It was redesignated and relocated on the new Epsilon platform in 2004, when the Malibu first debuted. The Malibu Maxx was part of this generation of the Malibu, which ran from 2003 to 2007. The Malibu sedan, on the other hand, continued to be produced for fleet orders until the 2008 model year. These vehicles are referred to as the Malibu Classic by General Motors. More information is available by clicking here. Suspension at the front The Malibu’s front suspension is comprised of a MacPherson strut that is attached to an aluminum knuckle and control arm assembly.

  1. The ball joint has a wear standard of 3.18 mm, which is considered to be moderate (0.125 in).
  2. When there is too much cross caster, the vehicle will pull in the direction of the side with the highest negative caster, causing it to swerve.
  3. An extra 1.75o of positive or negative camber can be achieved with the use of a cam bolt.
  4. When calculating cross-camber, take into consideration both the left side camber and the right side camber (cross-camber = left camber – right camber) as well as the width of the tire.
  5. For example, if the vehicle pulls to the left, the cross-camber should be set to a larger negative value, and the opposite should be true.
  6. Suspension at the back The rear suspension is a four-link design that is both durable and versatile, with built-in adjustments for camber and toe.
  7. The inner toe link cam bolt and nuts must be freed in order to adjust the rear toe.

Because the rear cams have extensive cross talk, it is usually a good idea to double-check both angles after making any adjustments to any cam.

The Malibu of this generation was the first to be equipped with electronic power steering (SS models have hydraulic power steering and do not require recalibration).

This technology makes use of a brushless direct current motor.

The Power Steering Control Module (PSCM) determines the amount of steering aid by combining the input from the steering shaft torque sensor with the vehicle speed, the calculated system temperature, and the amount of steering tuning selected.

It is necessary to calibrate the steering angle sensor and torque sensor following the completion of an alignment in order for the system to work correctly.

System harm may ensue if this is not done correctly.

Failure to do so may result in an imbalanced steering gear, which in turn may cause further pull issues.

Look up TSB 06-02-32-007G, which was issued on April 5, 2010, to read the whole text of the TSB.

Depending on how far away the clunk sounds appears to be, it might be straight in front of the driver.

When the vehicle is sitting motionless and the steering wheel is moved 90 degrees in either direction before first centering the steering wheel, the noise may be repeated in certain cases.

Intermediate shafts with a revised design went into production for the 2009 model year and have been the sole design available through dealers since September 2008.

The shafts of the updated or second design are painted black, whereas the shafts of the original form are bare metal.

According to the following instructions, the intermediate shafts of the redesigned design will not accept any sort of lubrication. Adding lubrication to the shafts of the second design will result in a clunk noise in a very short amount of time after application.

4 Causes of Engine Knocking Sound

A redesign and relocation to the new Epsilon platform occurred in 2004 for the Malibu. The Malibu Maxx was part of this generation of the Malibu, which ran until 2007. Although the Malibu sedan was phased out for the 2007 model year, it was still available for fleet orders in 2008. Malibu Classic is the name GM has given to these cars. Read More by visiting this link: Suspension on the front wheels For the Malibu’s front suspension, a MacPherson strut is connected to an aluminum knuckle and control arm assembly.

  1. The wear specification of the ball joint is 3.18 mm (0.125 in).
  2. An excess of cross caster can cause the vehicle to pull to one side, causing it to swerve to the other side of its path.
  3. An extra 1.75o of positive or negative camber may be obtained by using cam bolts on the wheels.
  4. When calculating cross-camber, take into consideration both the left side camber and the right side camber (cross-camber = left camber minus right camber).
  5. Adjusting the cross-camber to the left, for example, will make the car pull to the left, and vice versa.
  6. Suspension at the back of the vehicle There are camber and toe adjustments integrated into the rear suspension’s four-link design, making it a durable option.
  7. The inner toe link cam bolt and nuts must be unfastened in order to adjust the rear toe.
  8. Recheck both angles after any modification to the rear cams since the rear cams contain a large amount of crosstalk.
  9. For the driver’s assistance, there is no usage of hydraulics.
  10. By use of a worm and reduction gear positioned on the steering column housing, the motor aids in turning the steering wheel.

When the steering wheel is turned, the power steering control module (PSCM) analyzes the signal voltage from the steering shaft torque sensor to determine the amount of torque and steering direction being applied to the steering column shaft, and then commands the appropriate amount of current to the power steering motor to respond.

  1. The OBDII diagnostic connection is used to do this.
  2. Following an inspection and correction of tire, suspension, and alignment parameters, the steering position sensor and torque sensor calibration method should be carried out.
  3. Areas of Difficulty The steering intermediate shaft has been a source of contention for the Malibus of this generation.
  4. When driving at lower speeds and turning, drivers may experience a clunk noise that may be heard and felt in the steering wheel.
  5. The clunk sound can be produced by hitting a bump while turning.
  6. When the inner and outer components of the intermediate shaft come into contact with one other, this might result in a clunk noise.
  7. Because a second design shaft might have been put in any model year car, it is vital to identify it before proceeding.
  8. A second design shaft with black painted tube will need to be changed if it is discovered to be the cause of the noise (a very rare scenario).

According to the following instructions, any sort of lubricant will damage the intermediate shafts of the updated design. It will take only a few seconds after applying lubrication to the second design shafts for there to be a clunk sound.

4. Valvetrain Trouble

The combustion chambers of your engine are equipped with a number of valves. In order to allow the fuel and air combination to enter, intake valves must be opened. Once combustion has occurred, exhaust valves are activated, allowing the exhaust gases to escape. As part of the valvetrain, they are engineered to be rapid and smooth in their operation, both opening and closing. A valvetrain that is not functioning properly may produce a banging, ticking, or tapping sound. Inadequate clearance between the components, or hydraulic valve lifters that are in poor working order, might cause this problem to occur.

3. Crankshaft/Rod Knock

Piston movements within cylinders are sent to rod movements, which in turn are transmitted to the crankshaft through a series of connections. In order for the connecting rods and the crankshaft to function properly, rod bearings must maintain the right amount of clearance between them—just enough to allow oil to travel through while keeping the metal components from grinding against each other. Although this clearance can be raised if it has been too long since your last oil change or if your oil levels are low, it should not be done so.

This is produced by metal striking metal, and it is quite likely that your engine has sustained significant damage.

2. Pre-Ignition/Detonation Knock

During the combustion process in gasoline engines, a precisely timed spark ignites a fuel and air combination that is injected into the combustion chamber in order to produce combustion. It is conceivable, however, for gas to combust as a result of excessive compression before the spark has a chance to ignite it. As a result, a banging or pinging sound is produced. Though there are a variety of potential reasons of this, ranging from an inaccurate air/fuel ratio to timing that is slightly off, the most prevalent cause of this type of engine knock is the use of the incorrect type of gasoline.

However, there are a few automobiles that require premium gasoline, and fueling these vehicles with normal gas might result in this type of engine knock if done mistakenly.

1. Bad Knock Sensor

Ironically, engine knock may be induced by a knock sensor, which is intended to assist in the prevention of engine knock. If the knock sensor detects engine knock, it can send a signal to the car’s computer, which can then modify the timing or the fuel/air ratio to prevent the knock from occurring again. In the event of a faulty sensor, the engine may be instructed to make improper modifications, which may result in engine knock.

Bad Struts Noise ❤️ How Long Can You Drive With Bad Struts?

What exactly are struts? During driving, you may come across bumps or dips that cause the wheel assembly, chassis, and body to move in tandem. The struts of your automobile are solid car components that allow your car to move in unison when you hit a bump or dip.

When your struts begin to wear out, you will hear some unpleasant noises that you will have to deal with. Bad strut noise may range from clunking to knocking, and it’s not something to ignore. Struts are also included: Automobile repairs are EXTREMELY EXPENSIVE.

  1. The springs are tall and slim, and they serve as a vital element of the vehicle’s suspension. Combine a number of distinct suspension components into a single compact system. Support the weight of the vehicle
  2. Aids in the adaptation of the vehicle to road imperfections

The strut unit or assembly is found in the inner suspension assembly of all four wheels, and it is located in the center of the inner suspension assembly. Located at the rear and front of the vehicle, this unit is connected to the wheel assembly and the vehicle frame by means of bolts. When the strut assembly in your vehicle begins to show indications of failure or wear and tear, the defective assembly begins to have an impact on the amount of comfort you are able to enjoy. In addition, if you are entirely neglected, you may experience other problems.

Because of a defective and worn strut assembly, other components on the vehicle may be damaged as well.


If your strut assembly breaks entirely, you will have misaligned suspension as well as lower drag, which will put more strain and stress on the internal engine components, forcing them to fail. This has the potential to cause significant harm.


In addition, because the struts are a critical component of the overall front-end suspension alignment, when they fail to perform their functions, the suspension will drag. As a result, your tires, which are placed at the front of the vehicle, will collect far more heat than they should.


Because of the malfunctioning strut assembly and the increased wear on your vehicle’s tires, your vehicle’s vehicle axel and transmission will age prematurely and get damaged as a result. The expense of repairing something can be quite expensive.

Strut noise- A Telltale Sign that you have Bad Struts

The sound of faulty struts is not pleasant at all. In many cases, malfunctioning or worn-out struts may make noises that should act as an indication that your strut assembly is failing and needs to be replaced or repaired immediately. Drivers have reported hearing awful strut noises that sound like banging, rattling, and even clunking sounds when driving. A noise like this is typically heard when a vehicle is riding or moving over particular abnormalities in the road, such as bumps, potholes, items on the motorway, and so on.

When the driver rotates the steering wheel of the car, the bearing allows the strut assembly as well as the steering knuckle to spin or pivot as a result of the rotation.

Common Noises From Suspension And How To Repair Them

There is nothing nice about the noise made by bad struts. In many cases, malfunctioning or worn-out struts may make noises that should act as an indication that your strut assembly is failing and needs to be replaced or serviced. Bad strut noises, such as banging, rattling, and even clunking, have been reported by drivers. A noise like this is typically heard when a vehicle is riding or moving over particular abnormalities in the road, such as bumps, potholes, items on the motorway, and other obstacles.

As a result, when the driver turns the steering wheel of the car, the bearing allows the strut assembly as well as the steering knuckle to rotate or pivot. When many drivers crank the steering wheel of the car they are driving, they report hearing rattling, banging, and clunking sounds as well.


Deep banging noises usually indicate that the shock is the source of the problem. Before you do anything else, you may check for leaks (oil is the most common type of leak). Once a shock absorber begins to leak, the stability and rigidity of the shock absorber will begin to deteriorate. That ‘thump-thump’ sound you may have heard is the consequence of this process. If you hear a banging sound when you compress the brakes on your automobile, especially when the vehicle is practically at a complete stop, the cause may be a problem with the back brake linings that have become stuck.

If the linings are the source of your banging sound, the noise should stop.

What about knocking sounds while driving at a slow and steady pace?

If you’re hearing a banging sound while traveling at a slow and steady speed, it’s possible that one or more of your suspension components has come free. The most common reasons are: damaged shock mounts, loose stabilizer links, bar bushings that are out of place and loose, and shock absorbers that have lost their effectiveness.

Knocking sounds while driving on bumps and cracks in the road

When you’re driving and you start to hear knocking sounds coming from either the rear or the front wheels – especially when you’re going over potholes, cracks, or even bumps in the road – you can usually track the problem back to the stabilizer link. You can elevate your automobile or use a jack to raise it in order to identify and diagnose any loose links in the suspension system. Take a hold of the link that is located lower on the page and see if you can shake it. If you can feel it slipping, you’ve got the banging sound on your hands.

What about knocking sounds as you turn your steering wheel?

Although the steering wheel might be difficult to turn in some situations, this is a warning indication that your suspension is about to give way. Don’t make the mistake of thinking that your troublesome and jammed steering wheel/steering column joint is a broken or a shattered shock mount bearing. Perhaps you should take your vehicle to a certified auto technician for a proper diagnosis of the issue.

Loud metal-to-metal noise While Driving Over Potholes

Metal-on-metal sounds when you drive over a control arm bushing are generally indicative of a defective control arm bushing. Control arm bushings have a propensity to wear down and dry up over time, especially when exposed to extreme temperatures. Additionally, they are prone to cracking. In most cases, a defective and desiccated control arm bushing will have an adverse effect on your steering system. If you travel at a high rate of speed, you may also notice the wheels of your automobile trembling.

They can be replaced if they are in the wrong position or if they are in the wrong position.

Are New Struts Supposed To Make Noise? Are My New Struts Bad?

Having excellent replacement struts is a strong possibility in your situation. However, it is possible that the noise you are experiencing after the repair is caused by worn or loose mounting hardware. As a result, bring your vehicle back to the shop and have an auto specialist inspect the mountings. He or she will check to see that they are properly fastened and will also search for any other worn suspension components that may be present.

If the noise is coming from the strut, your mechanic will need to inspect the top bearing plate and, if required, repair it -at no cost to you once you have made your payment-.

Does my vehicle need to be aligned after I have strut Replacement?

Yes. In addition, your mechanic will do an alignment to complete the repair. Many auto technicians recommend that you get your vehicle aligned after you have new struts fitted. It is true that the manufacturer of the car does not give alignment advice in a few instances. In most cases, though, your auto specialist will align the vehicle.

Why Is The Spring Seat On The Replacement Strut Bigger Than On The Original Strut I’m Getting Replaced?

Many replacement struts are supplied with a lower spring seat with a fairly big diameter, which is common in the industry. This is a precautionary measure rather than a flaw. Additionally, this arrangement is in place to prevent a damaged coil spring from coming into direct contact with the tire’s tread. Before sending you on your way, your auto specialist will grant clearance and thoroughly inspect all of the parts and components.

Can You Put Struts On Wrong Side?

An extremely large diameter spring seat is seen on the bottom spring seat of many aftermarket replacement struts. Rather from being a flaw, this is a safety precaution. Furthermore, this design is in place to prevent a damaged coil spring from coming into direct contact with the tire’s tread. After providing clearance and inspecting all of the parts and components, your car specialist will discharge you.

What Happens If A Strut Breaks While Driving?

There will be one region of our car that travels a little more freely, farther, and quicker than the other side when we have a damaged strut. The wear and tear on the other suspension components will be increased as a result of the damaged strut. It is possible that other components will fail. Furthermore, if you have damage to other suspension components, you will be looking at a more expensive repair price.

How Do I Quiet Noisy Strut Mounts?

Clunkiness is not produced by the struts, but rather by a worn top bearing plate and a worn upper bearing bearing. You may need to double-check to see whether you changed any of the strut assembly’s components, or if you replaced the strut cartridge as a precaution. The bearing plate and bearing should always be replaced with the strut — in fact, with the exception of the spring, pretty much everything in the strut assembly should be replaced with the strut.
