What are some signs of a failing CV axle?
You might notice a clicking or ratcheting noise when making a tight turn. Also look for a drip of oil near the wheel, or a spatter of grease on the backside of the wheel.
How does the CV joint work?
Also known as a Cardan joint, a CV joint uses a ball inside a cup with bearings that move in tracks on the ball. This system allows torque to be transferred while the joint itself can be turned at even an extreme angle.
What happens if a CV axle fails?
A failed CV axle at highway speed can thrash around and cause a great deal of damage to the transmission and other assemblies under the hood.
Usually, a CV axle will last the whole lifespan of the vehicle, but not always. If you suspect yours might be failing, don't wait – shop Advance Auto Parts for OEM-quality CV axles for your vehicle.
Transferring the power from your car's engine and transmission to the wheels, axle shafts, also called CV axle shafts, play an important role. The CV joints can wear out, usually after a torn, previously protective boot allows dirt into the joint. This is typically indicated via certain noises such as clicking or grinding.
