MOOG Chassis Products Suspension Control Arm P/N:RK621951
Locate the rear wheel and keep suspension movement in check with the MOOG RK642797 Control Arm. It installs as a direct-fit replacement in the rear lower rearward position for a wide range of Mercedes-Benz SUVs, including the 2012-2016 Mercedes-Benz GL350, 2016-2018 Mercedes-Benz GLE350 and 2017-2019 Mercedes-Benz GLS450 — see the "Vehicles it fits" section for the full list.
Worn control-arm bushings can produce clunking over bumps, imprecise handling, or uneven tire wear; if a failed arm or its bushings are the cause, this replaces them. The listed applications use two, and this control arm is sold individually — replacing both sides together as a matched set is recommended for balanced handling. Country of origin: Turkey.
