Help keep rear-suspension movement quiet and controlled with the Mevotech Supreme Knuckle Bushing MS50477, a rear lower knuckle bushing that installs as a direct-fit replacement for the listed applications. It fits many vehicles, among them the 2004-2011 Chevrolet Malibu, 2005-2010 Pontiac G6 and 2003-2011 Saab 9-3 (see the "Vehicles it fits" section for the full list and engine-level applications). It locates the rear knuckle and cushions the joint, helping isolate road vibration and limit unwanted movement in the rear suspension.
- High-grade natural rubber construction: molded for increased durability.
- OE-quality fit and performance: built to work like the original bushing on the listed applications.
- Rear lower position: designed for the rear lower knuckle location.
Worn or cracked rubber can allow excess movement, clunking, or imprecise handling; if a failed knuckle bushing is the cause, this replaces it. Consult the vehicle service information for the correct fasteners and whether they may be reused.
