What is a CV axle in a car?

What is a CV axle? It’s a shaft with constant-velocity (CV) joints that transfers the rotating torque to one of the drive wheels in a car. It might also be called a half shaft or drive shaft. A typical front-wheel drive car has two CV axles (CV shafts), one at each front wheel.

What are the symptoms of a bad CV axle?

Bad CV axle symptoms include loud clicking when turning or accelerating and harsh vibration when driving. If the boot is damaged, grease can accumulate on the inside edge of the tire, on the drive shaft, or other underside components near the boot. You can learn more signs of worn CV axles here.

What’s the best way to replace a cv shaft?

Push the shaft towards the transmission (which should compress the inner and outer CV boots), and have your buddy strike the end of the axle shaft gently to get the CV snap rings to compress and move through the transmission’s differential spline. Ensure that the CV nut is on the shaft to prevent damage to the threads.

What are the CV joints on a front wheel drive car?

Typical CV axle (shaft) of a front wheel drive car with a Rzeppa outer CV joint and closed tripod-style inner joint. The inner CV joint can work under small angle too. The design of outer CV-joint allows it to transfer the rotation motion at greater angles. Both CV joints are packed with grease and sealed with rubber or plastic boots.

Why do CV axles wear out so quickly?

The joint is lubricated with grease and covered by a rubber boot that protects it from dirt and debris. Because the CV axles are the direct link that transfers the power of the engine to the wheels, they are subject to high levels of stress over time and will eventually wear out…

How does a constant velocity ( CV ) axle work?

Constant-velocity (CV) joints allow the drive shaft to transmit power through a variable angle, at a constant rotational speed, without a considerable increase in friction. The CV joints are also responsible for a smooth transfer of engine power regardless of the turning angle of the steering wheel.

Can a CV axle be replaced at home?

You can do the work yourself, but you’ll need to be prepared. Can I Fix or Replace My CV Axle At Home and How Much Will It Cost? You absolutely can replace your CV axle at home, but you’ll need to be at least remotely comfortable using a jack, jack stands, and power tools.
