Keep your Mercedes-Benz front suspension located and tracking true with the Delphi control arm TC2978, the front left rearward lower suspension control arm that links the wheel knuckle to the chassis, guides suspension travel, and helps hold wheel alignment. It's a direct-fit replacement for the 2010-2011 Mercedes-Benz E350 and 2010-2011 Mercedes-Benz E550. If a worn or damaged original arm is behind clunking over bumps, imprecise steering, or uneven tire wear, this replaces it.
