Cushion the rear suspension and keep the knuckle located where the shock mounts with the Mevotech Supreme Knuckle Bushing MS404310. This suspension knuckle bushing drops in as a direct-fit replacement at the rear-at-shock position for many vehicles, among them the 2011-2015 Ford Explorer, 2010-2016 Ford Taurus and 2009-2017 Ford Flex; see the "Vehicles it fits" section for the full list.
- Natural rubber construction: made from high-grade natural rubber for increased durability.
- OE-quality fit and performance: built to deliver factory-level fit and performance.
- Rear-at-shock location: cushions and locates the knuckle where the shock attaches, helping absorb road inputs and limit unwanted movement.
Worn or cracked rubber can allow excess play, clunking on acceleration, deceleration, or over bumps, and imprecise handling. If a failed bushing is the cause, the MS404310 replaces it, helping return the intended cushioning and location. Inspect the bushing before ordering to confirm it is the source of your symptoms.
