Many vehicles use a pair of CV axles to transfer rotational force to the front drive wheels. The axles often require replacement due to issues, such as torn boots and worn joints.
There’s a good chance you’ll experience CV axle problems at some point during your driving career. The good news is, if you’re handy and have the proper tools, you can save a substantial amount of money by replacing a faulty CV axle yourself.
What is a CV Axle?

In a front-wheel drive layout, the CV axles connect the transaxle to the wheel hubs. Rotational force from the engine is transferred to the transaxle, which, in turn, transfers that force to the CV axles. The CV axles then turn the wheel hubs, which serve as a mounting point for the wheel and tire assemblies.
Each CV axle has an inner and outer CV joint. The joints allow the CV axle shaft to move up and down as the vehicle travels over bumps. Also, the outer joints pivot to allow the front wheels to turn. Grease-filled boots cover the inner and outer joints.
How to Replace a CV Axle
The procedure for replacing a CV axle will vary, depending on the year, make, and model of the vehicle. So, it’s important to consult the replacement instructions for your application in a
