Keep the front wheel located and the steering tight with the Mevotech Supreme control arm CMS101230, a front left lower suspension control arm and ball joint assembly that installs as a direct-fit replacement for the 2013-2015 Mercedes-Benz GLK250 and 2010-2015 Mercedes-Benz GLK350. It positions the wheel relative to the chassis and pivots on an integrated ball joint so the suspension can travel and the wheel can steer. See the Buyer's Guide tab for engine-specific applications.
As a Mevotech Supreme lower control arm, this one-piece unit carries the control arm bushings and the ball joint together. Signs the original may need replacing include clunking or knocking over bumps, uneven tire wear, or loose, wandering steering — if a worn control arm or ball joint is the cause, replacing this assembly replaces both. Diagnose the cause before ordering.
