Keep the front wheel precisely located and steering tight with the Mevotech Supreme control arm and ball joint assembly, part number CMS10143. This front left lower rearward unit is a direct-fit replacement for a range of Mercedes-Benz sedans and coupes — including the 2003-2009 E320, 2007-2009 E550, and 2007-2011 CLS550 — with the ball joint already pressed in so there's no separate joint to install. See the Buyer's Guide tab for the full list of covered applications.
The control arm locates the wheel while its integrated ball joint lets the suspension move as the wheel steers. Worn bushings or a loose ball joint can bring on clunking over bumps, steering wander, or uneven tire wear; if a failed original arm is the cause, this assembly replaces both the arm and its ball joint in one part. Mevotech Supreme parts are built for high-usage commercial and passenger vehicles, SUVs, fleets and working trucks, with Labor Saver designs intended to make the job faster.
