A clunk over bumps, uneven tire wear or a pull in the steering can mean a worn lower arm or ball joint. Sway bar links, tie rod ends, shocks and a wheel bearing can be behind those signs too, so find the cause before buying. If the arm or its joint is at fault, this control arm and ball joint assembly replaces both in one piece.
Fits
The 2017-2019 Mercedes-Benz GLS550, the 2017-2019 Mercedes-Benz GLS63 AMG and the 2018-2019 Mercedes-Benz GLS450 each take one on the front right, and the arm fits other vehicles too. This listing is one arm; the front left of that axle is a separate part and is normally replaced at the same time.
