Audi A4 A5 A8 Control Arm Bushing 4N0407515 8W0407515

Control Arm Bushing — 4N0407515 / 8W0407515

Restore the precise, confident handling your Audi was engineered to deliver. These control arm bushings are the critical rubber-to-metal interface between your suspension control arm and the chassis — absorbing road vibrations, reducing noise, and keeping your wheels perfectly aligned through every corner.

Worn bushings are one of the most common causes of vague steering, clunking over bumps, and uneven tire wear on high-mileage Audis. Replacing them brings back that solid, planted feel that makes driving an A4, A5, or A8 such a pleasure.
