CV Boots

CV Boots Faultfinding and Diagnosis:

Constant velocity (CV) joints are usually reliable and largely trouble-free. The two main failures are wear and partial seizure.

Wear in the outer joint usually shows up as vibration at certain speeds, a bit like the vibration caused by an unbalanced wheel. To determine if the joint is worn, a driver should find a big empty parking lot and drive the car slowly in tight circles, left and right. Worn joints will make a rhythmic clicking or cracking noise. Wear in the inner joints shows up as a "clunk" or "pop" when applying power or, if severe, when lifting off the throttle.

Partial seizure causes a strange "pattering" sensation through the suspension. It is caused by the joint overheating, which in turn is usually caused by the outer joint gaiter / cv boot having split, allowing the joint to throw out its grease. If caught in time, one can clean the joint carefully, repack with grease and replace the gaiter / cv boot. Kits which include the grease, gaiter / cv boot, and retaining clips are available from most automotive manufacturers. Some universal gaiters / cv boots are split lengthwise enabling them to be fitted without having to disassemble the wheel hub and CV joint.
