Control Arm Bushing

Control Arm Bushing – How to Know if Repairs are Needed

Control arm bushings connect the control arm to the frame of the vehicle. Control arms pivot through the bushings. Most control arm bushings are made from torsional elastic rubber, 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. Some applications have steel control arm bushings that rotate on threads instead of a straight shaft.
