Beck/Arnley Suspension Control Arm and Ball Joint Assembly P/N:102-8243
Keep the left-front suspension located and the wheel under control with the Beck/Arnley Suspension Control Arm and Ball Joint Assembly 102-7957, a front left upper control arm that arrives with its ball joint pre-installed for a complete, one-piece replacement. It drops in as a direct-fit application for the 2015-2017 Mercedes-Benz CLS400, 2012-2018 CLS550, 2014 CLS63 AMG, 2014-2018 CLS63 AMG S, 2014-2016 E250, 2013-2016 E350, 2015-2016 E400, and 2010-2014 E550 — see the Buyer's Guide tab for engine-level detail. The control arm anchors the wheel to the chassis while the ball joint lets the assembly pivot through steering and suspension travel; worn bushings or a loose ball joint can bring on clunking over bumps, loose steering, or uneven tire wear.
