Dial in precise front-suspension geometry with the Mevotech Supreme control arm — the Suspension Control Arm and Ball Joint Assembly CMS101456, a front right upper unit that combines the control arm and its integrated ball joint in a single serviceable part. It installs in the front right upper position on a wide range of Mercedes-Benz S-Class and Maybach sedans, including the 2014-2017 S550, 2015-2017 S550E, 2015-2017 S600, 2014-2015 S63 AMG, 2015-2019 S65 AMG, 2018-2021 S560, 2019-2020 S560E, 2018-2020 S450, plus the Maybach S550 (2017), Maybach S600 (2016-2017), Maybach S560 (2018-2020) and Maybach S650 (2018-2020) — see the Buyer's Guide tab for the full list.
The control arm locates the front wheel and connects the steering knuckle to the chassis, while the integrated ball joint permits steering and suspension articulation through the wheel's travel. Clunking or knocking over bumps, loose or wandering steering, and uneven front tire wear can be signs the original arm or ball joint may need replacing — diagnose the cause before installing this part.
