Can a CV axle make a clunking noise?
In addition to humming, a defective CV axle can develop any number of clicks, pops and clunks as the damage to the axle joints worsens. If a clunking noise is heard while speeding up or slowing down, it can mean damage to the inner and outer CV joints.
Difficulty Steering
The CV axle transfers all the torque from the powerplant to the ground, as such, if the axle is out of place, making the car steer is likely to be an issue. This happens when you try to steer, but the car is not keen on changing direction. If this does happen, be sure not to drive the car before the issue is resolved.
Grease Leaking
Constant-velocity joints are developed to efficiently transfer power through a variable angle without any losses of power of additional friction. These CV joints are protected by rubber boots which are often filled with Molybdenum disulfide, or as we know it – grease.
Screeching, Clacking, Or Knocking Sounds
If you hear any screeching, clacking, or knocking sounds, especially while turning, it could be a definite sign of a worn-out driveshaft/CV axle. This tends to happen if the CV axle starts to leak, and if not attended in an earlier stage it could result in an entire drive shaft replacement.
Bounciness And Lack Of Control
Whenever your CV axle is near its imminent death, it usually starts to bounce the car in a fairly dangerous manner. When this does happen, it feels like you are off-roading, even while driving on perfectly smooth tarmac. As mentioned, this can be dangerous, so don’t drive the car until the issue is taken care of.
Vibrations
Experiencing mild vibrations while driving a car is completely normal because the engine and many other components vibrate even while idling. However, if the vibrations are unnaturally intensive or they also cause weird noises, it is likely a symptom of a suffering CV axle.
Weird Noises While Steering The Car
A common symptom of a faulty CV axle is unnatural sounds coming from the front wheel wells. The sound somewhat resembles thumping and it only appears while turning the wheel. This is of course unnatural and is most likely tied to a faulty CV axle.
Worn Out Joints
As previously mentioned, CV joints are used to transfer energy without any friction or loss of power. This means that they are essential as far as an efficient and comfortable ride is concerned. Even though they are made to last a long time, they can sometimes wear out prematurely if the driving conditions are less than ideal.
What does a bad CV joint sound like?
Ans: A defective CV can sound like a loud click, popping, or clunks as the damage worsens. Frequent brake noise at low speed (caused by damage to the outer CV joints) makes grinding noises when making a tight turn at a low rate. A bad CV joint also causes a vibration felt in the steering wheel and floorboard of the car.
Why does my CV make a noise?
When your CV joints are not well-lubricated, it will increase the friction, preventing your CV axle to freely rotate. If your CV joints are not lubricated enough, it can cause your joints to make noise each time the axle starts turning.
What happens if your boot clamps are damaged?
If your boot clamps are damaged, it will cause your CV boot to loosen up, allowing the accumulation of debris into your CV joint. This effect will cause an inner CV joint clunk, which will eventually lead to the formation of noises from your CV joint while driving your vehicle.
What is a CV joint?
All FWD (front-wheel-drive) vehicles have CV joints attached to the ends of the drive shaft. These joints are of two types; the ball-type joint used for the outer CV joint and the tripod-type joint used for the inner CV joint. These joints are critical mechanical components of your vehicle’s suspension system that allows you to drive your car ...
Why do CV joints wear out?
One of the most common issues with your CV joints is when your boots are damaged, torn, or cracked. When you have broken boots, grease will begin to leak out through the boot, and this can cause an accumulation of dirt on your joint, which can cause your CV joint to wear out a lot faster and might even fail to function as a result of the absence of lubrication and presence of corrosion. The CV joint, also being contaminated by debris, is another effect that slowly damages your joint.

You will experience this because the joints are worn out and due for replacement . This is an entirely normal case as every mechanical component will eventually need to be replaced with time.
What does CV joint noise mean?
A worn-out CV joint also makes clunking sounds when shifting from drive to reverse; these sounds are usually deafening when accelerating in turns. You might hear cracks or breaks sound in the rubber or plastic boots around the CV joint. The car can also shudder or shake under heavy acceleration.
Symptoms
The most common symptom of a bad cv joint is clicking noise when turning or accelerating.
Preventing CV Joint Failure
Visually inspect near the CV joint for grease leaks, especially on the exterior CV boot. Also, check if the CV joint clamps are loose or broken.
Replacing a CV Joint
Early detection of damage to a CV boot is beneficial because, in this case, the boot is replaced, and the joint is repacked with new grease. Replacements are typically sold as a kit specific for the vehicle, and it will include a new CV boot, grease, and new clamps. It is less expensive than having to replace the driveshaft or the entire CV joint.
Replacement Cost
The cost of replacing a CV boot alone can vary from $350-$800. If you are going to the trouble of removing the CV joint to replace the boot, you may want to consider replacing the CV joint/axle.
What does a bad CV joint do to a vehicle?
