Keep your front suspension tracking true with the Mevotech Supreme control arm and ball joint assembly, part number CMS101338. This Mevotech Supreme suspension control arm mounts in the front right upper forward position, locating the wheel and providing the pivot point that lets the suspension travel while holding alignment. It drops in as a direct-fit replacement for the 2008-2009 Mercedes-Benz C230, 2010-2012 C250, 2008-2014 C300, 2008-2015 C350 and 2012-2014 E350 — see the Buyer's Guide tab for engine-level fitment.
Engineered in-house with application-specific upgrades, this unit combines the control arm and a pre-assembled ball joint into one ready-to-install assembly:
Signs a control arm or its ball joint may need replacing include clunking or rattling over bumps, loose or wandering steering, uneven front tire wear, or a vibration. If a worn arm or ball joint is confirmed as the cause, this assembly replaces both in one part.
