CV axles transfer power from the transmission to the wheels while allowing for suspension movement and steering angle. A torn CV boot or worn joint is one of the more recognizable automotive noises — a rhythmic clicking that shows up specifically when turning.

Signs of a CV Axle or Joint Problem
- Clicking or popping noise when turning, especially at low speed
- Grease visible flung around the inside of the wheel or tire
- A torn or cracked rubber boot visible on the axle
- Vibration that increases with vehicle speed
- Clunking noise when accelerating or shifting from reverse to drive
The CV Boot's Job
The CV joint is packed with grease and sealed by a rubber boot that keeps dirt and water out. Once that boot tears — from age, road debris, or a cracked seal — the joint loses lubrication and starts wearing quickly, eventually leading to the clicking noise this problem is known for.
Why the Noise Happens on Turns
A worn CV joint has more play in it, which becomes most noticeable when the joint is working at an angle — exactly what happens when the wheels are turned. That's why the classic symptom is a clicking sound specifically during turns, especially in a parking lot or driveway at low speed.
Catching a Torn Boot Early
If a torn boot is caught before the joint itself is damaged, sometimes just the boot can be repaired. Once the joint has been contaminated and is worn, the axle assembly typically needs to be replaced. Regular inspections can catch a torn boot before it becomes a bigger repair.

Frequently Asked Questions
Why does my car click when I turn?
This is a classic sign of a worn CV joint, usually caused by a torn boot that let dirt and moisture into the joint. It's worth having inspected before the wear progresses.
Can a torn CV boot be repaired without replacing the whole axle?
If it's caught early, before the joint itself is contaminated and worn, a boot repair may be possible. Once the joint has significant wear, the axle assembly typically needs replacement.
Is it safe to drive with a clicking CV joint?
It's best not to wait too long. A worn joint continues to deteriorate and can eventually fail, so having it inspected once you notice clicking is the safer approach.
