Overhaul

Print

The CV boot allows the CV joint to rotate and pivot, while retaining the lubricant and protecting the CV joint from water and debris.

A torn, damaged or leaking CV boot should be replaced immediately. Loss of lubricant will cause the joint to overheat and damage it. Because these are precision-machined components, they can be quite expensive to replace. The cost of the boot is about 10-20% of the cost of a CV joint.

Typically a failed CV joint makes a clicking noise during acceleration, especially when accelerating from a stop and turning.
