Keep the front suspension located and your steering geometry on target with the Mevotech Supreme control arm and ball joint assembly (P/N CMS101570). This front left (driver-side) lower forward unit installs as a direct-fit replacement for the listed applications: the 2014-2017 Mercedes-Benz S550, 2018-2020 S450, 2018-2021 S560, 2017 Mercedes-Benz Maybach S550, and 2018-2020 Maybach S560 — see the Buyer's Guide tab for full engine-level fitment.
As a Mevotech Supreme lower control arm, it links the subframe to the steering knuckle and locates the front wheel through suspension travel, while the integrated ball joint lets the knuckle pivot for steering and articulation and the rubber bushings help isolate road inputs. Clunking over bumps, uneven front tire wear, or loose, wandering steering can be signs the original arm's ball joint or bushings are worn. Mevotech's Labor Saver™ designs and hardware help speed installation.
