Bushings and insulators are the flexible connections between the hard parts. They serve as shock absorbers and vibration isolators, providing a pivot point on which the hard parts articulate.

Air suspensions are more complex that mechanical suspension, and have more wear parts like bushings, air springs, shock absorbers, and air controls that require inspection and periodic servicing.

The mechanic will be able to see if there are major leaks (shock absorbers are filled with fluid), worn mounts or bushings, or physical damage to the shock absorbers, such as dents, which can ...

Bushings are rubber or metal parts that help absorb shock. A small amount of looseness in the suspension or steering that doesn’t get fixed can lead to rapid tire wear, cutting tire life by as ...
