A failing front control arm shows up as clunks over bumps, loose or wandering steering and uneven tire wear, and a worn S10 control arm is a common culprit on high-mileage GM compact trucks. The Mevotech Supreme Suspension Control Arm and Ball Joint Assembly (CMS20355) is a front right upper unit that positions the wheel and, through its integrated ball joint, lets the steering knuckle pivot as the suspension travels. This control arm and ball joint assembly is a direct-fit replacement across a broad range of GM applications, including the 1988-2004 Chevrolet S10, 1995-2005 Chevrolet Blazer, 1985-1994 Chevrolet S10 Blazer, 1992-2005 GMC Jimmy, 1985-1990 GMC S15, 1984-1991 GMC S15 Jimmy, 1991-2004 GMC Sonoma, 1991 GMC Syclone, 1992-1993 GMC Typhoon and 1991-2001 Oldsmobile Bravada — see the Buyer's Guide tab for the full list.
- Superior toughness: sintered bearings for longer-lasting performance.
- Stamped steel construction: built to meet or surpass OE specifications, with a protective surface treatment that resists rust build-up.
- Quick, easy installation: secures to the vehicle with the part-specific castle nut and cotter pin provided.
- Simple to service: includes a 135-degree SAE grease fitting, and added knurling locks the rubber control arm bushing to the sub-frame for an optimal fit.
The ball joint is designed with a thicker, stronger flange to resist deformation during installation, and Mevotech Supreme's Labor Saver design helps make the swap faster. Because the ball joint is integrated, replacing this arm renews both the arm and its joint in one part. Control arms wear on both sides, so inspect the opposite side and replace as needed for balanced handling.
