Beck/Arnley Suspension Control Arm P/N:102-8078
Steady your Mercedes-Benz's rear suspension geometry with the Beck/Arnley control arm 102-8283, a rear upper rearward arm engineered as a direct replacement that matches OE form, fit, and function. It fits a wide range of Mercedes-Benz SUVs and wagons, including the 2007-2009 GL320, 2010-2016 GL350, 2006-2015 ML350, 2016-2018 GLE350, 2017-2019 GLS450, and 2008-2012 R350 — see the Buyer's Guide tab for the full list of 30 applications.
A control arm links the wheel hub to the chassis and pivots to locate the wheel, maintaining suspension travel and alignment while its bushings help isolate road vibration. Worn arms or bushings can bring on clunking, uneven tire wear, and steering that wanders — if the original arm is the cause, this replaces it.
