OE Replacement Construction

This suspension control arm assembly is built as a direct OE replacement for the front right upper forward location. The steel casting/forged control arm, pre-greased ball joint, and included bushings are selected to restore suspension geometry and maintain consistent handling on Audi A4, A4 allroad, A4 Quattro, A5, A5 Quattro, A5 Sportback, RS5, RS5 Sportback, S4, and S5 vehicles. Part number 527-056 is also referenced for interchange with Delphi TC3797 and OE number 8W0407506C.

Common Issues This Part Addresses

• Clunking or knocking from the front suspension
• Excessive play in the upper control arm or ball joint
• Uneven tire wear caused by worn suspension components
• Loose or imprecise steering feel
• Directional instability during braking or cornering

Installation Notes

Verify vehicle fitment by year, model, and front right upper forward position before installation. This assembly uses a threaded ball joint stud, a 14 mm ball joint thread diameter, and a 12.3 mm mounting hole diameter. Because the ball joint is already installed and the unit is pre-greased, installation focuses on removing the worn assembly and transferring the mounting points to the vehicle suspension.
