Delphi Suspension Control Arm P/N:TC8289
Delphi TC2863 control arm for the 2015-2020 Audi A3 and other vehicles is the front left lower arm that connects the wheel to the body and lets the suspension move.
A worn suspension control arm can show up as a clunk over bumps, uneven tire wear or wandering steering. Before you replace this arm, rule out worn tires, an alignment problem or a loose sway bar link, since those produce similar symptoms. This listing is a single arm, and the one on the other side of that front axle is normally replaced at the same time. The 2015-2020 Audi A3 takes one.
It is a direct-fit replacement for the 2015-2020 Audi A3 Quattro and works as a 2015-2020 Audi S3 control arm.
