GM 14026980 F, Bushing

Raise the rear of the car and support it with jackstands positioned at suitable locations under the frame. Support the rear axle with a mobile jack such as a transmission jack or floor jack, which can be rented on a daily basis from a rental agency or some auto parts stores. Remove the wheels and brake drums. If the right control arm bushing is being replaced, loosen the parking brake adjustment nut and disconnect the forward cable from the parking brake equalizer lever by prying forward on the equalizer lever. Then twist the equalizer lever and disengage it from the pivot mount on the body. Remove the bolts that attach the brake line brackets to the chassis. Remove the lower shock attaching nuts and bolts. Remove the spring(s). Remove the bolts that secure the control arm bracket to the underbody and allow the control arm to rotate downward. Remove the control arm bracket from the control arm. Removal of the old bushing and installation of the new one must be done using special GM tools or equivalents. When installing, the cutouts on the rubber portion of the bushing must face toward the front and rear. Remount the control arm bracket to the control arm and check that it is positioned at a 45° angle to the lower edge of the control arm. When the proper angle is set, tighten the nut and torque it to specs. Install the various components by reversing the removal procedure. Do not torque the lower shock nuts to specifications until the car has been lowered and its full weight is on the suspension. Adjust the parking brake.
