One of the most common suspension items to replace or service on the 911 is the constant velocity, or CV joints that connect the wheels to the transmission. These bearings, packed in grease, get a tremendous amount of mileage through the years, and thus have a tendency to wear out after about 100,000 miles or so. One of the clear signs that the joints need replacing is the distinct sound of a clunk, clunk, clunk coming from the rear axle when the car is in motion.

In some cases, the boots that cover and protect the CV joints will be torn and need replacing. The procedure for replacing the boots is very similar to the procedure for replacing the entire joint. New boots should be installed each time a new CV joint is installed.
