Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC9384
Delphi TC4670 front left lower control arm with ball joint for the 2022-2026 Audi Q4 e-tron and other vehicles connects the wheel to the body. The ball joint lets the wheel pivot for steering and move over bumps.
A worn control arm or ball joint can show up as a clunk over bumps, loose or wandering steering, or uneven tire wear. These signs alone do not prove this arm is the problem; a worn sway bar link can knock in a similar way. Replace the left and right arms together as a pair; this listing is one front left arm.
This arm fits the 2022-2026 Audi Q4 e-tron, the 2022-2026 Audi Q4 e-tron Sportback and the 2021-2024 Volkswagen ID.4. Each takes one arm at the front left, and the right side is a separate part.
