If you’ve heard a clicking sound when turning, your CV axle may be trying to tell you something. Here’s what this component does and how to recognize a failing one before it leaves you stranded.
What Is a CV Axle?
CV stands for constant velocity. The CV axle transfers power from your transmission to the wheels while flexing with your steering and suspension movement. Its joints are packed with grease and sealed by rubber boots. When a boot tears, the joint loses its grease, picks up dirt and water, and wears out — which is how most CV axles fail.
Bad CV Joint Symptoms
- A clicking or popping noise when turning (the classic sign of a worn outer joint)
- Grease flung onto the inside of the wheel or under the car
- Vibration that grows with acceleration
- A clunk when shifting into drive or reverse
- A visibly torn or leaking CV boot
A freshly torn boot is okay for a short time, but once the joint starts clicking, the axle can fail completely and leave you unable to drive — so it’s best addressed promptly.
How CV Axle Replacement Works
Rather than trying to repack a worn joint, technicians fit a complete CV axle assembly: they lift the vehicle, remove the wheel, disconnect the axle from the hub and transmission, install the new axle, and torque everything to spec. It’s typically a one-to-two-hour job our mobile mechanics do at your location.

Frequently Asked Questions
Can I drive with a torn CV boot?
For a short time, yes — but once the joint clicks, replace it promptly, because a failed axle can leave you stranded.
How long do CV axles last?
Often well over 100,000 miles, but a torn boot dramatically shortens that by letting the grease out and contaminants in.
What causes the clicking when I turn?
A worn outer CV joint, usually after a boot has torn and the joint has lost its grease.
