Delphi Lateral Arm P/N:TC8845
Delphi TC4990 rear left upper lateral arm for the 2018-2026 Audi A5 Quattro and other vehicles locates the rear wheel within the suspension.
A clunk over bumps, uneven rear tire wear or loose-feeling handling can mean a worn lateral arm. These signs alone do not prove the arm is at fault, since a tired shock absorber can cause a similar knock.
This lateral arm is a direct-fit replacement for the 2018-2025 Audi S4, the 2016-2025 Audi A4 Quattro and many other Audi models. If your car is not named here, look it up in the "Vehicles it fits" section.
