Suspension Ball Joint Replacement
What is a ball joint?
Ball joints are part of the suspension system, and consist of a ball and socket that's encased in a lubricant-filled rubber boot. They link the steering knuckle (which supports the wheel hub, bearing and wheel) to the lower and upper control arms. They also allow the suspension to move freely up and down and aid in steering the vehicle
What are the symptoms related to a bad ball joint?
A "clunk" or "knock" when turning or going over bumps can indicate a problem with a ball joint. The sensation is often felt in the floorboard.
A repair technician may notice if a ball joint is leaking lubricant from a worn or torn boot during an inspection or a related repair. Excessive wear on the inside or outside edges of the front tires can sometimes indicate problems with the ball joints, as well.
Can I drive with a ball joint problem?
A vehicle with a significantly worn ball joint should not be driven. If the ball joint fails completely, the control arm can detach from the steering knuckle, meaning you will lose control of the car.
A car with a ball joint that is just starting to wear out can be driven, but as the wear increases, so do the chances of premature tire wear and poor handling. If you suspect that a ball joint is beginning to wear, have a technician evaluate the problem as soon as possible.

How often do ball joints need to be replaced?
There is no set replacement schedule for ball joints, though most vehicles will need to have them changed at some point. Most ball joints will last for 100,000 miles or more. Rough driving habits may shorten the life of these parts.
