CV Axle
The CV axle transfers power from the transmission to the wheels while flexing to handle steering and bumps. When the protective boot tears, grease leaks out and dirt gets in, leading to a clicking noise on turns and vibration. Replacing the CV axle restores smooth, quiet power delivery to your wheels.

Frequently asked questions
What does a failing CV axle sound like?
The classic sign is a clicking or popping noise when you turn, especially at low speed. You may also feel vibration while accelerating.
Is it safe to drive with a bad CV axle?
Only for a short time. If it fails completely the axle can break and leave you stranded, so it's best to repair it promptly.
Can just the boot be replaced instead of the whole axle?
If caught very early, sometimes. But once grease is lost and the joint is worn, replacing the full axle is usually more reliable and cost-effective.
