There are a few things that can go wrong in constant velocity (CV) axle assembly. Leaking grease and everyday wear can make its parts worse. How do you know if your CV assembly is failing? Below is a list of negative CV features and other important information.
How Do You Say If Your CV Axle Is Wrong?
Here are some of the features that can point to a bad CV shaft:
Clicking a sound when you turn
Damages in a CV axle due to frequent use can make the joints lose. As the external joints are unstable, they may produce a distinct sound described by some people as a click or a pop. This sound is most noticeable when making sharp or fast curves while driving around corners.
You will hear a strange clicking sound on the vehicle’s side with the damaged CV shaft.
Clunking sound when you slow down or accelerate
You may hear abnormalities or knocking sounds from the inner CV joint assembly when you slow down or speed up.
The sound may come from a completely different source, but hearing it should be a cause for concern.
Grease exposed to the bottom of the vehicle
The CV boot is something that keeps CV joints lubricated to make them function correctly. It is made of high-quality rubber that does not break easily.
However, if the boot is damaged, the grease inside it will flatten on the vehicle’s bottom as the axle turns.
