Keep the front suspension tight and precise with the Mevotech Supreme Front Upper Ball Joint MS10578, a direct-fit front upper ball joint for a wide range of Mercedes-Benz cars. It fits many Mercedes-Benz vehicles, among them the 2007-2012 Mercedes-Benz SL550, 2007-2011 Mercedes-Benz CLS550 and 2007-2011 Mercedes-Benz CLS63 AMG — see the "Vehicles it fits" section for the full list and engine details.
The ball joint connects the front upper control arm to the steering knuckle, letting the wheel steer and travel while locating the suspension. Worn joints may show up as clunking on acceleration or over bumps, loose steering, or uneven tire wear — signs this part may need replacing.
