What does a bad cv axle sound like?

Turning sounds such as popping or clicking

This implies that the outer CV axle is worn or damaged. To test this situation, put the car in reverse, turn the steering wheel to one side, and drive backward in a circle (first check the rearview mirror!). If the noise becomes more audible, it verifies the diagnosis and the necessity for a new CV shaft assembly.

A “clunk” when accelerating, decelerating, or shifting into drive.

Excessive play in the inner joint in FWD applications, either the inner or outer joints in a RWD independent suspension, or the driveshaft CV joints or U-joint in a RWD or AWD powertrain causes the noise. To test the condition, reverse the car, alternating between accelerating and decelerating. A faulty inner joint is confirmed if the clunk or shudder is more apparent.

A buzzing or snarling sound.

This can be caused by insufficient lubrication in either the inner or outer CV axle as a result of a broken or split boot. This symptom, however, is most commonly caused by worn or broken wheel bearings, a poor intermediate shaft bearing on equal length halfshaft transaxles, or worn shaft bearings within the transaxle.

When accelerating, there is a shudder or tremor.

This might be due to inboard or outboard joint movement, but the most likely reason is a worn inboard plunge joint. A faulty intermediate shaft bearing on transaxles with equal length halfshafts, or defective motor mounts on FWD cars with transverse-mounted engines, can also create similar vibrations.

A vibration that becomes stronger as you go faster.

It should be noted that a deteriorating CV axle is seldom the source of this symptom. The most likely reasons are an out-of-balance tire or wheel, an out-of-round tire or wheel, or a bent rim.

Grease on the Inside of Your Tires

The CV Axle boot is carefully greased to guarantee peak performance. If the boot is damaged, the lubricating grease may spill onto your wheels. This isn’t as noticeable as a sudan click or knock, but it’s a quick method to validate any concerns you have about the health of your halfshaft. If you suspect a damaged CV boot, inspect the inside of your tire for oil; if none is discovered, you may have a whole new issue on your hands.

A split in the boot

This is self-evident, although the majority of the other symptoms mentioned might have other explanations; still, if all signals indicate north, it’s preferable to travel north. In other words, if you display multiple symptoms of a blown CV axle, there is only one definite method to determine the cause: examine the axle. To do so, get underneath your car and examine the CV axles that link to your wheels. If a rip in the rubber boot is discovered, it must be replaced. Often, it is all that is required. However, if a ripped boot is not repaired soon, the joint might run without oil and get damaged. At that time, replacing the entire CD axle is usually the best option.

CV boot problem

When your boots are destroyed, torn, or cracked, one of the most frequent problems with your CV joints is that the grease leaks out through them. Grease will seep out of the boot when it has been broken, and this can cause dirt to accumulate on your CV joint, which can hasten its deterioration and render it unable to operate because of a lack of lubrication and corrosion. Another consequence that slowly damages your joint is the CV junction being contaminated by debris.

When grease appears from your CV boot through a tear or crack, it indicates that your boot or CV joint is broken. Grease will be present within the interior of your wheel rim and on the inside of your drive wheel region in the event of severe damage. When you accelerate or make quick turns, these factors cause CV joint noise.

If you’re driving quickly and make a turn, you’ll notice an increase in noise. And if your CV joint is faulty, it’s possible to cause extensive damage by continuing to drive.

Boot clamps that have been bent or broken

The boot clamps keep your CV boots in place. These clamps ensure that the boots are well sealed, preventing any contact with your CV joint. If your boot clamps are broken, your CV boot will loosen up, allowing debris to accumulate in your CV joint. This effect will result in an inner CV joint clunk, which may lead to noises from your CV joint while driving.

If you hear any odd noises coming from your joints, check your boots and clamps for the source of the problem.

Lubrication deterioration

When your CV joints are not well-lubricated, the friction between them will rise, preventing your CV axle from freely rotating. If your CV joints aren’t lubricated enough, they may produce noise when the axle starts to spin. When driving your vehicle, you’ll hear inner CV joint noise. The noise becomes louder when you’re moving quickly. You might only hear the problem while traveling at a low speed.


Axles that have been in use for a lengthy time will produce steering noise or joint noise. This is due to the fact that the joints are worn out and must be replaced. Because every mechanical component will ultimately need to be replaced, this is a typical occurrence. They are sturdy yet do not endure indefinitely.

The axles are what connect the front wheels to the car. If an axle begins to fail, you’ll notice your car starts pulling to one side as it loses power. And if the axle breaks completely, that wheel won’t turn at all. Even though the engine may still run, signs of a broken axle mean your car won’t move anymore.

Never drive your car if one of the axles is broken as it’s not safe. If you start hearing a bumping, clicking or grinding noise when taking turns, then your axle isn’t broken yet–but it probably will be soon. Once your axle fails, there’s a chance that you won’t be able to control the car anymore. This increases the risk of getting into an accident or crashing.

Early detection of damage to a CV boot is crucial because, if caught in time, the boot can be replaced without having to replace the entire driveshaft or CV joint. Replacement boots typically come as part of a kit specific to the vehicle, and will include new grease and clamps along with the boot itself. This method is less expensive than buying an entirely new driveshaft or CV joint.

It’s possible that the damage is more extensive than a cracked boot, and the entire CV joint is too worn. CV joints cannot be restored; they must be replaced with new components. Furthermore, if you don’t replace just the CV joint because it won’t be sold separately, you may have to replace the complete CV axle.

Depending on your car, the instructions to replace the CV boots, joints or driveshaft will be different. Replacing the CV joint is a difficult task that will require extra money if you have to buy new tools to finish it.

If you have the necessary equipment and knowledge, you may save money by changing the CV axle yourself. Most CV axle replacements cost between $75 and $200. Of course, the precise price will be determined by a variety of criteria, including the year, make, and model of your car.

F.A.Q Bad CV axle noise, what are the bad CV axle noise symptoms?

How long will a CV joint last once it starts making noise?

It is relatively safe to drive with a bad CV joint for around 4-5 months, but after 6 months it is best to take your car into a mechanic.

Can CV axle clunk over bumps?

The most frequent problem with CV joints is when the protective boot cracks or is damaged. When the weight of the car puts pressure on this region and causes it to shift back and forth and side to side, you may hear a clicking, clunking, or popping sound coming from this area (when compared with other components).

How long can you drive on a bad axle?

The answer will vary depending on which CV axle you’re looking at. It might take weeks, months, or even years to complete. However, the typical lifespan of a bad CV axle is around five to six months. This knowledge alone does not imply that you should increase your deadline by a few days.

How do you diagnose CV axle noise?

Then, drive in a circle around the rear of the car while turning the steering wheel all the way to one side. Turn the steering wheel in the other direction and repeat the process. If you detect a distinct clicking or cracking sound, there’s a good chance an outer CV joint is damaged.


A bad axle will make a squealing or grinding noise when you turn it. If you’re not sure whether your axle is bad, take your car to a mechanic and have them take a listen. It’s important to get any potential problems with your car fixed as soon as possible – not only for the safety of yourself and your passengers, but also because an axle that’s on the verge of failing can cause other parts of your car to break down too. Have you ever had to replace an axle on your car? What was the process like?
