Beck/Arnley Suspension Control Arm P/N:102-8397
Beck/Arnley 102-7837 front left lower control arm for the 2012-2015 Audi A4 and other vehicles joins the front left wheel to the body and lets it move with the suspension. This Beck/Arnley control arm, also called a suspension control arm, comes without a ball joint, as the OE design does.
A clunk over bumps, uneven tire wear or a pull to one side can mean a worn control arm. A worn ball joint, a worn bushing, a sway bar link or an alignment problem can be behind the same signs, so find the cause before buying. This listing is one arm for the front left, since each side of the axle takes one. The front right is a separate part ordered on its own, and both sides are normally replaced together.
This lower control arm for the 2012-2015 Audi A4 matches OE form, fit and function, and it also suits the 2015-2025 Porsche Macan and the 2012-2018 Audi A6 Quattro. Open the Buyer's Guide tab to check your exact model and engine.
