Delphi Lateral Arm P/N:TC8458
Delphi TC4489 rear lower lateral arm for the 2022-2026 Audi Q4 e-tron and other vehicles helps locate the rear wheel in the suspension. Its materials match OE specifications.
A clunk over bumps, uneven rear tire wear or vague handling can mean a worn arm. A worn shock, a loose wheel bearing or unbalanced tires can be behind these too, so find the source before ordering. Plan on replacing the arms on both sides of the rear axle together: the car takes two, and this listing is one.
This lateral arm fits the 2022-2026 Audi Q4 e-tron, the 2022-2026 Audi Q4 e-tron Sportback and the 2021-2024 Volkswagen ID.4.
