The trailing arm bushings join the axle and pivot point on the body of the vehicle. They are part of a trailing arm suspension in your vehicle. The front trailing arm consists of a set of bushings attached to a bolt that runs through these bushings to hold the trailing arm to the chassis of the vehicle. The purpose of the trailing arm bushings is to cushion the movement of the suspension while holding the wheel on the correct axis. The bushings absorb minor vibrations, shocks, and noise from the road to make for a smoother drive.
