Replace a worn rear upper control arm and keep the rear wheel properly located with the Mevotech Supreme Lateral Arm and Ball Joint Assembly CMS40158. This rear upper unit is a direct-fit replacement for the 2002-2005 Ford Explorer, 2005 Ford Explorer Sport Trac, 2003-2005 Lincoln Aviator, and 2002-2005 Mercury Mountaineer, combining the lateral arm and its ball joint into one serviceable assembly. The arm locates the rear wheel and controls its lateral position, while the ball joint lets the suspension articulate over the road.
Signs the original assembly may need replacing include clunking or knocking from the rear suspension over bumps, uneven rear tire wear, or looseness in the rear wheel. Diagnose the cause before replacing, since these symptoms can have other sources. See the Buyer's Guide tab to confirm the engine and trim for your vehicle.
