A "clunk" or "pop" when going over bumps or turning can indicate a problem with a ball joint.

Excessive inner or outer tire wear can sometimes be attributed to problems with the ball joints.

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.

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. Get this fixed by a RepairPal Certified Shop

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.

To diagnose a worn ball joint, a shop will raise the vehicle on a hoist and then grasp the tire at the top and bottom and rock the wheel back and forth. A worn ball joint will present a clunking sound or sensation when this test is performed. The technician will also look for a torn or leaking boot on the ball joint. A worn ball joint may also be suspected if the tires are showing signs of unusual wear on the inside or outside edges.

To replace a ball joint, with the car lifted, the technician will first remove the front wheel. Then, the ball joint is disconnected from the control arm and the steering knuckle, the suspension is separated to allow the ball joint to come free, and the new part is installed. Some vehicles require that the steering knuckle be disconnected from the strut in order to get to the retaining nut on one side of the ball joint. Either way, the tension between components in the suspension may make this process difficult.

The replacement of the ball joints will affect the alignment's settings, so we recommend a four-wheel alignment when the ball joints are replaced.

RepairPal recommends getting a four-wheel alignment after the ball joint has been replaced. If the tires show signs of significant wear, new tires would also be a good idea.
