Setup, Compatibility & Care
Installation should only be performed by experienced mechanics using a repair manual specific to the Audi B9 platform. The control arm is designed for the front axle, right side, upper position. It is highly recommended to replace the paired article number (39312 01, which is the left-side equivalent) simultaneously to ensure balanced suspension geometry. Always use new hardware where required by the manufacturer and perform a professional four-wheel alignment immediately after the component is secured to prevent premature tire degradation. Inspect the rubber bushings periodically during routine oil changes for signs of cracking or perishing.
