What makes CV joints go bad?

What Causes a CV Axle to Fail? CV axles and joints may wear faster than normal if the CV boot is ruptured. When this happens, the joints lose grease and are no longer properly lubricated. Moisture, water, and other road debris can also get inside the ruptured boot, making the CV joints vulnerable to faster wearing.

Are worn CV joints dangerous?

A severely worn out CV joint can even crumble while you’re driving and make the car undrivable. If this happens it is incredibly dangerous because you may lose control of the vehicle entirely. It is not safe to drive with a damaged CV joint. In a worst-case scenario, your CV joint will fail completely.

What are the symptoms of a worn CV joint?

The most common symptom of a worn outer CV joint is a clicking or popping noise when turning. Usually the noise gets louder when accelerating in turns. In the worst cases, a badly-worn outer CV joint can even disintegrate while driving, which could create a potentially hazardous situation.

How can you tell if you have a bad axle?

Bad vehicle vibrations after a collision with a bad pothole, unexpected curb, or other objects may indicate axle damage. Vibrations may be accompanied by an unusual rumbling noise underneath the vehicle, strange tire wobbling, or sluggish driving and steering, which may indicate a bent axle.
