Locate the rear axle and hold your alignment steady with the Mevotech Supreme Lateral Arm CMS401129, a direct-fit replacement for the 2007-2024 Ford Expedition and 2007-2024 Lincoln Navigator. This is the rear lower forward lateral arm, the link that positions the axle side-to-side and helps keep the rear wheels tracking and aligned as the suspension moves.
A worn or bent lateral arm can let the rear axle shift out of position, which may show up as clunking or knocking from the rear over bumps, uneven rear tire wear, or a vehicle that wanders and won't hold an alignment. If a failed lateral arm is the cause, this replaces it and restores the intended locating point for the axle. Because these arms install in pairs across the axle, it's good practice to inspect and replace both sides together for balanced suspension geometry.
