CV and Drive Axles

CV joints: How they work, and how to spot early signs of failure

Controlled velocity (CV) joints and drive shafts transfer energy from your engine to your wheels, propelling your car forward. CV joints transmit smooth and continuous energy to your wheels, even on turns or bumpy roads. They are a key component of your car’s drive train system.

If you notice early signs of failure—grease drips or clicking sounds on turns—you need to have your car looked at by a professional immediately to reduce the cost of repair.

Below, you will learn:

  • What CV joints do
  • How to spot signs of CV joint problems such as grease stains on your garage floor or clicking sounds on turns

Common CV joint problems (and their solutions)

CV joints are a key part of your drive train system. To maintain their flexibility, they are heavily lubricated with a molybdenum disulfide grease and protected with a rubber boot. Both the lubricant and the boot are necessary for continued CV joint protection and function.

Most CV joint problems stem from loss of lubrication or wear of the rubber boot. Here are some of the common CV joint questions we get:

  • “Why are there grease spots under my car?”
    It’s likely that the rubber boot protecting your CV joints has cracked or worn out. In most cases, the most cost-effective method of repair is to just replace the CV driveshaft as an assembly.
  • “Why is there a clicking noise when I turn?”
    This is typically a sign of damage to the ball bearings inside your CV joint due to lack of lubrication or leaks. If this is the case, we might need to completely replace your driveshaft.

At the first sign of CV joint problems, you need to bring your car in. Neglecting CV joint repairs can lead to drive axle and CV joint failure, rendering your car undrivable.
