Control Arm Bushing
Rare Parts stocks all types of control arm bushings.
Control arm bushings connect the control arm to the frame of the vehicle, and help isolate vibration.
Control arms typically have bushings at the pivot points. Most control arm bushings are made from torsional elastic rubber, or polyurethane, which will wind up when the control arm is not sitting in its normal functioning position. As control arm drops or climbs, the torsional elastic rubber will wind up causing the control arm to return to its normal position.
Older applications use steel control arm bushings that rotate on threads of the control arm shaft. In this configuration the steel bushings and shaft wear against each other, and need to be replaced at the same time.
