Locate the front wheel, hold alignment geometry, and pivot the suspension through one integrated joint with the Mevotech Supreme control arm (P/N CMS101280). This front right lower rearward control arm and ball joint assembly drops in as a direct-fit replacement for the 2009-2014 Mercedes-Benz CL550, 2012-2013 S350, 2008-2011 S450, 2024 S500 and 2007-2013 S550 — an S550 control arm built for high-usage commercial and passenger vehicles, SUVs and fleets.
As a Mevotech Supreme suspension control arm, it connects the frame to the steering knuckle and lets the wheel travel while the integrated ball joint pivots for steering. Worn control arms or ball joints can bring on clunking over bumps, loose or wandering steering, and uneven tire wear; if a failed arm or joint is the cause, this assembly replaces both in one part.
