Keep your Mercedes-Benz tracking true with the Beck/Arnley control arm 102-8284, a rear left upper control arm that locates the wheel and lets the suspension move through its travel while holding the proper alignment geometry. It drops in at the rear left upper center position across a wide range of Mercedes-Benz SUVs, including the 2012-2015 ML350, 2012-2014 ML550, 2013-2016 GL550, 2016-2018 GLE350 and 2017-2019 GLS450 — see the Buyer's Guide tab for the full list of 22 applications.
Application-specific for the listed vehicles. Clunking or knocking from the rear suspension, vibration, uneven tire wear, or loose, wandering handling can be signs a control arm or its bushings are worn. Have the cause diagnosed first, then if the arm is at fault this unit replaces it.
