Removal (Cadillac)
- Raise vehicle and support at both sides of frame. Place jack under center of axle housing and lift it until it just starts to raise housing. If equipped with Electronic Level Control, disconnect link at height sensor lever. Remove both shock absorbers from lower mounting.NOTE: Shock absorbers act as rebound stops on rear suspension system. DO NOT remove shocks unless both axle and frame are firmly supported.
- Remove rear lower control arm nuts. Place jack under front of differential to relieve tension on lower arm bolts, then remove lower control arm bolts and arms. Remove upper control arms. Disconnect propeller shaft and support out of way with wire so front "U" joint does not support weight of shaft.
- Remove jack from under front of differential. Remove brake hose from junction block on housing and plug openings. Slowly lower axle and remove from vehicle.NOTE: Do not allow axle to turn during removal. Springs may snap from seats, causing damage or personal injury.
