Upper and lower ball joints are designed to fit snugly inside a lubricated casing. If the casing loses lubrication, dries out, or the linkage becomes loose, wheel alignment may be affected. A loose ball joint can also result in suspension noise and uneven tire wear. Because ball joints act as the link between the wheels and other suspension components, a bad joint can conflict with normal steering capabilities. In extreme cases, a worn ball joint that fails may fall out of its casing and cause a collapse of the suspension system. Clunking sounds, poor handling, and unnatural pulling are all signs of bad ball joints. In some cases, ball joints may require replacements. If you plan on avoiding a ball joint failure, be sure to consult your owner’s manual for the maximum allowable wear on your suspension system’s ball joints. Our replacement ball joints will restore full functionality to your suspension system.
