Cushion road impacts and steady your steering with the KYB strut mount kit SM5276, a front suspension strut mount and bearing assembly that drops in as a direct-fit replacement for the listed applications: the 2000-2005 Buick LeSabre, 1998-2005 Buick Park Avenue, 1998-1999 Buick Riviera, 1998-1999 and 2001-2003 Oldsmobile Aurora, 2000-2005 Cadillac DeVille, 1998-2004 Cadillac Seville, and 2000-2005 Pontiac Bonneville. Old, hardened vibration insulators transmit jarring, noise and vibration into the cabin; this KYB suspension strut mount kit is designed to replace them with fresh components matched to each application.
If worn front strut mounts are the source of your steering vibration, memory-steer, or impact noise, this kit replaces the mount and bearing together. See the Buyer's Guide tab for the full engine-level fitment on your vehicle.
