Beck/Arnley Suspension Control Arm and Ball Joint Assembly P/N:102-7780
BECK ARNLEY 102-8135 front right lower control arm with ball joint for the 2015-2023 Mercedes-Benz C300 and other vehicles connects the front wheel to the chassis. Also listed as a control arm and ball joint assembly, it lets the wheel pivot and move up and down with the suspension.
A worn control arm or ball joint can show up as a clunk over bumps, loose or wandering steering, or uneven tire wear. Worn sway bar links, tie rod ends or strut mounts can be behind those signs too, so find the cause before you buy.
The 2015-2023 Mercedes-Benz C300, the 2019-2023 Mercedes-Benz E450 and the 2020-2023 Mercedes-Benz E350 all take this arm, along with other Mercedes-Benz models. It matches OE form, fit and function. This listing is one arm for the front right; the front left is a separate part, and the two are normally replaced together. If your car is not named here, look up its year and model in the "Vehicles it fits" section.
