What causes a CV axle to click?
What causes a CV axle to click?
When the wheel is turned, the ball bearings move quite a bit. When it is worn out, the ball bearings will move to a point, then give way. In this process it “pops” to the end of it’s travel, causing the popping noise you are talking about. A CV joint will last quite a long time.
What are the symptoms of a worn CV joint?
If the car continues to be driven with a damaged CV joint boot, the CV joint will wear out and eventually fail. 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.
What makes a CV joint make a popping or clicking sound?
The ball bearings are involved, but the noise isn’t because they are dropping. What happens is when the boot splits, the grease starts oozing out (less lubricant) and dirt gets in causing wear. One of the jobs of grease is to take up excess slack in the joint (not that there is much in the first place when it’s not worn out).
Where are the CV joints on a front wheel drive car?
In front-wheel drive cars, ball-type CV joints are used on the outer side of the drive shafts ( outer CV joints ), while the tripod-type CV joints are mostly used on the inner side ( inner CV joints ). The CV joint boot looks OK. Click for a larger photo
What causes a CV joint in a boot to break?
The most common problem with the CV joints is when the protective boot cracks or gets damaged. Once this happens, the grease comes out and moisture and dirt get in, causing the CV joint to wear faster and eventually fail due to lack of lubrication and corrosion. Usually outer CV-joint boots break first,…

When does a CV axle become loose and click?
When CV axles become excessively worn, the constant velocity joints will become loose and click when turning or accelerating. The clicks may become louder or more pronounced during sharper and faster turns and will be heard on the side with the faulty CV shaft.
