The control arm bushings on B-BODY vehicles have a significant impact on your vehicle's ride, comfort, handling, acceleration, noise and vibration. When the vehicle leans (rolls) in a turn, one side of the chassis moves up relative to the rear axle and the other side moves down. The control arms must twist to allow for the axle to articulate, this causes the control arm bushings to bind.
