Beck/Arnley 102-7838 front right lower control arm for the 2012-2015 Audi A4 and other vehicles connects the right front wheel to the body. This Beck/Arnley control arm, also called a suspension control arm, pivots as the wheel moves over bumps.
A worn front right lower control arm can show up as knocking over rough pavement, steering that drifts or uneven front tire wear. A worn sway bar link, strut mount or ball joint can be behind those signs too, so find the cause before you buy an arm.
The 2012-2015 Audi A4 and the 2015-2025 Porsche Macan take this arm, along with many other vehicles, and it matches the OE form, fit and function. If your car is not named here, put its year and model into the "Vehicles it fits" section to see whether this arm applies. This listing is one arm for the front right; the front left of that axle is a separate part, and the two are normally replaced together.
