Keep your rear suspension properly located and your rear tires tracking true with the Mevotech Supreme Lateral Arm (CMS861164). This rear upper lateral arm drops in as a direct-fit replacement for the 2010-2023 Lexus GX460, 2003-2024 Toyota 4Runner, and 2007-2014 Toyota FJ Cruiser.
A lateral arm locates the rear suspension side-to-side, controlling wheel position as the suspension cycles through its travel. If your original arm is worn or bent, replacing it helps restore the intended geometry.
Signs this arm may need replacing include clunking or knocking from the rear, uneven or accelerated tire wear, and an alignment that won't hold. Diagnose the cause before replacing, since these symptoms can have other sources.
