Audi Ball Joints

Audi ball joints consist of a bearing stud and socket enclosed in a steel housing. This bearing stud is tapered, threaded and fits into a matching tapered hole in the steering knuckle. A special moly grease is used to lubricate the ball joint along with a protective boot that covers the joint area and prevents dirt from entering the Audi ball joint assembly. Audi ball joints serve as the pivot points between the tires and suspension and are also used to support chassis weight. Audi's incorporate two types of ball joint designs. One design bolts the ball joint onto the control arm using fasteners (see tables to right). The second design incorporates the Audi ball joint as a integral part of the control arm (see image below).

An Audi ball joint is an important suspension component. Audi ball joints, along with other suspension components, should be inspected yearly. It is important to carefully inspect Audi ball joints, particularly if you are experiencing any handling problems. Audi ball joints wear out over time and can cause handling problems as they begin to deteriorate. If you wait until an Audi ball joint fails, you may find yourself stranded on the side of the road. A worn ball joint has the potential of completely popping out of its socket when it fails which can result in some serious damage.

If you think that your Audi ball joint needs replacing there are some symptoms to check for. Most commonly a knocking or squeaking noise can be heard in the front end suspension when driving over bumpy roads. Other signs associated with worn out Audi ball joints is erratic steering, wandering, and uneven tire wear.

You can save money on replacement costs by replacing the tie rod or tie rod ends along with the Audi ball joint. These parts work in conjunction and it can be smart preventative maintenance to replace them both at once.
