Delphi Lateral Arm P/N:TC8458
Delphi TC4712 rear right upper lateral arm for the 2017-2026 Audi Q7 and other vehicles is a rear suspension link that helps hold the wheel in position.
A clunk over bumps, uneven rear tire wear or a loose feel from the rear end can point to a worn lateral arm. A worn rear shock or another rear suspension link can be behind those signs too, so find the cause before buying.
This arm is listed for a wide range of Audi models, led by the 2017-2026 Audi Q7, the 2019-2026 Audi A6 Quattro and the 2019-2026 Audi A8 Quattro. This listing is one arm for the rear right upper position; the left side of that axle is ordered separately and is normally done at the same time. On the 2017-2026 Audi Q7, this position takes one arm.
