What is a CV Axle Assembly?

A CV axle assembly is a drivetrain component on a vehicle that delivers power from the transmission to the wheel. It is commonly used in front-wheel-drive systems, but can also be found on all-wheel-drive, and even some rear-wheel-drive vehicles with independent suspensions.

How does a CV Axle Assembly work?

CV axles are different from the straight axles of old, where a pair of rods ran through a cylindrical tube, connected on one end to a gear box (differential), and, on the other end, to the wheel hub. The CV axle assembly features joints at each end of a short shaft that move to accommodate the many angles it faces as part of a front wheel drive system. Also known as a "half shaft", the CV axle assembly is connected to the transmission on one end, and to the wheel hub on the other. Near each end is a universal joint that is capable of moving in several directions while the shaft is spinning. That way, it can travel over bumps in the road with the suspension, while at the same time it can turn with the steering.

What are the symptoms of a bad CV Axle Assembly?

The CV (constant velocity) joints near each end of the axle assembly slide back and forth inside a cup, or housing. The joints are lubricated with grease and sealed inside a pair of rubber boots. These boots hold the grease inside, and they keep the dirt and grime outside. Otherwise, the CV joints would deteriorate rapidly. But, over time, the boots can become worn and can crack or tear. Some of the grease escapes and dirt enters the joint, causing it to break down. When this happens, the CV joint develops excessive play in its bearings. A repetitive clicking sound may be heard when the vehicle is accelerating through a curve - such as on a freeway entrance ramp. A clunking sound may be noticed upon deceleration. Vibration may be felt when traveling at highway speeds. A visual inspection of the CV axle shaft will usually reveal grease seeping from a crack or tear in one of the boots.

Can I drive with a bad CV Axle Assembly?

As a CV axle assembly begins to deteriorate, and symptoms start to appear, the vehicle is still driveable. Once the process of breakdown in the CV joints begins, however, it does not reverse. The problem will continue to worsen. If left for too long, a CV joint can break apart, causing considerable damage to the steering and suspension and possibly a loss of control of the vehicle. At the least, the vehicle will be undrivable. The axle should be replaced sooner than later - before it fails.

How often do CV Axle Assemblies need replacement?

A CV axle assembly should last the lifetime of the vehicle. Unfortunately, it is not uncommon for an axle to fail. If a CV joint boot cracks or tears, it is only a matter of time before the joint wears out. If a boot is compromised, it can be replaced. If the problem is recognized before other symptoms happen (clicking or clunking sounds when driving), the life of the axle can be prolonged. Replacement of the boots on a CV axle requires that the entire assembly must be removed from the vehicle and disassembled. Because of this labor-intensive approach - and because there is no guarantee how long the joint may last after being compromised - many owners choose to have the entire assembly replaced instead.
