Locate the front suspension and keep the ball joint swinging smoothly with the Delphi control arm and ball joint assembly TC3394, a front left lower unit that integrates the lower control arm with its ball joint in one serviceable piece. It's a direct-fit replacement for many vehicles, among them the 2008-2013 Mercedes-Benz C300, 2012-2013 Mercedes-Benz C350 and 2012-2013 Mercedes-Benz E350 — see the Buyer's Guide tab for the full list and engine-level fitment.
Worn control arm bushings or a loose ball joint can show up as clunking over bumps, wandering steering, or uneven tire wear; if the original front left lower arm is the cause, this assembly replaces it. It covers the left side only and is sold individually — replacing both sides together is recommended for balanced handling.
