The CV (constant velocity) joint has become the standard on most all front wheel drive cars.
The CV joint allows the drive shaft to transmit power from the differential to the wheels at variable angles.
While there is wear on these joints any time the car is in motion ,most failures are due to the CV joint boot rupturing allowing the grease to escape and dirt ant and debris to enter the joint.
A simple inspection of the CV joint boots on a regular basis will allow you to identify a problem before it causes considerable damage to the joint.
Most manufacturers offer replacement boots for the CV joints and it is far less expensive to replace the boot than to replace the entire CV joint (or in some cases the axle shaft assembly) after it has failed.
A clicking sound emitting from the front wheel when steering hard in one direction is usually an indication that a CV joint is bad.
