Quick facts
- Part: Delphi TC3090 control arm
- Also called: suspension control arm
- Fits: 2009-2016 Audi A4 and other vehicles
- Position: Rear right upper
- Condition: New
A worn suspension control arm can show up as a clunk over bumps, uneven tire wear or vague handling. These signs alone do not prove the arm is at fault, since a tired strut mount can knock over bumps as well.
Fits
This control arm is a direct-fit replacement for the 2009-2016 Audi A4, the 2015-2022 Porsche Macan and the 2010-2018 Audi A8 Quattro, among other vehicles. The 2009-2016 Audi A4 takes one on this side; the left side is a separate part, and the two are normally replaced together. If your car is not named here, open the "Vehicles it fits" section and check your exact model and engine.
