Keep the rear leaf spring located and cushioned with the Mevotech Supreme Leaf Spring Bushing (MK6544). This rear-position bushing isolates the leaf spring at its mounting point, allowing the spring to flex and pivot while dampening road noise and vibration. It's a direct-fit replacement for the 1988-1996 Buick Regal, 1988-1997 Oldsmobile Cutlass Supreme, 1988-1996 Pontiac Grand Prix, 1990-1994 Chevrolet Lumina, and 1997 Oldsmobile Cutlass — see the Buyer's Guide tab for full engine-level fitment.
Worn or deteriorated leaf spring bushings can produce clunking or squeaking over bumps and allow excess spring movement. If a failed bushing is the cause of those symptoms, this rubber bushing replaces it and helps quiet the rear suspension. Inspect both sides and replace as directed by the vehicle service procedure.
