Beck/Arnley Suspension Control Arm P/N:102-8078
Keep your Mercedes-Benz's rear suspension located and controlled with the Beck/Arnley Suspension Control Arm 102-8283 (also written 1028283). This rear upper rearward control arm positions the wheel and helps maintain proper suspension geometry and alignment. It installs as a direct-fit replacement across a wide range of Mercedes-Benz GL, GLE, GLS, ML, and R-Class models — including the 2007-2009 GL320, 2010-2016 GL350, 2006-2015 ML350, and 2008-2012 R350. See the Buyer's Guide tab for the full list of applications and engines.
A worn control arm or its bushings can show up as clunking or knocking over bumps, imprecise steering, or uneven tire wear. If a failed rear upper rearward control arm is the cause, this Beck/Arnley unit replaces it to help restore correct wheel location. Replacing the matching arm on the opposite side at the same time is good practice for balanced handling.
