OE-Style Suspension Replacement

This Dorman 520-983 assembly is built as an OE-style replacement for the front left lower rearward suspension position on 2005-2011 Audi A6, 2005-2011 Audi A6 Quattro, and 2007-2011 Audi S6. It uses a steel casting/forged control arm design with a pressed ball joint and rubber bushings to match the original suspension layout on these vehicles. This part cross-references Delphi TC1879 for the same application.

Common Problems This Part Addresses

• Front-end clunking or looseness from worn control arm bushings
• Uneven steering response caused by ball joint wear
• Directional instability during braking or lane changes
• Suspension noise from deteriorated rubber bushings
• Restoring alignment stability after control arm wear

Installation Notes and Tips

Verify the front left lower rearward position before ordering, since this assembly is application-specific. Inspect adjacent suspension components, fasteners, and alignment settings during replacement. Because the ball joint is installed and the unit is pre-greased, installation focuses on proper positioning, torque, and final alignment checks.

Quality Assurance

Dorman backs this control arm assembly with an industry-focused evaluation process to help ensure consistent fit, ride quality, and suspension behavior on the listed Audi A6, Audi A6 Quattro, and Audi S6 applications.
