Restore a tight, quiet suspension connection with the Mevotech Supreme Suspension Control Arm Bushing MK6580, a rear lower bushing that cushions and locates the control arm where it pivots against the vehicle chassis. It installs as a direct-fit replacement for the 2009 Buick LaCrosse, 2000-2002 Buick LeSabre, 1997-2001 Buick Park Avenue, 1995-1999 Buick Riviera, 1995-1999 and 2001-2003 Oldsmobile Aurora, and 2000-2003 Pontiac Bonneville — see the Buyer's Guide tab for engine-level details.
A worn control arm bushing can show up as clunking or knocking over bumps, imprecise steering, or uneven tire wear. If a failed rear lower bushing is the cause, this Mevotech Supreme unit replaces it to help restore proper alignment and a controlled ride. Bushings on an axle wear at a similar rate, so inspect the opposite side and replace in matched pairs where appropriate.
