Axle bushing is an independent plain bearing that is inserted into a housing to provide a bearing surface for rotary applications; this is the most common form of a plain bearing.[8] Common designs include solid (sleeve and flanged), split, and clenched bushings.
Bushings are used in control arms, stabilizer bars, ball joints, tie rods, shock absorber mounts, and other suspension and steering parts, as well as in engine and transmission mounts. They wear and crack from age, heat, exposure to road salt and lubricants, and the stress of frequent movement and weight loads.
