Mevotech Supreme Suspension Control Arm and Ball Joint Assembly P/N:CMS86142
Keep your front suspension located and your steering predictable with the Mevotech Supreme control arm, MPN CMS101289. This front right lower forward control arm and ball joint assembly installs as a direct-fit replacement for the listed applications: 2009-2014 Mercedes-Benz CL550, 2012-2013 S350, 2007-2013 S550, 2008-2011 S450, and 2024 S500 — see the Buyer's Guide tab for engine-level applications.
As a lower control arm, it locates the wheel and, through its integrated ball joint, lets the front suspension and steering move through their normal travel. If a worn control arm or a loose ball joint is behind clunking over bumps, steering wander, or uneven front tire wear, this Mevotech Supreme suspension control arm replaces the whole assembly in one part. Diagnose the cause first, since these symptoms can have other sources.
