Detailed Description

Delphi applies OE-focused engineering to its aftermarket steering and suspension portfolio, using dimensional and material analysis to match the original part as closely as possible. TC2816 is a rear lower rearward suspension control arm for Audi A6, Audi A6 Quattro, and Audi S6 applications, including track rod configurations noted in the fitment data. The stamped steel body, natural rubber bushings, and black finish support stable suspension geometry and consistent ride control in replacement service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Address

• Rear suspension looseness or wandering caused by worn control arm bushings
• Clunking or knocking from the rear lower suspension area
• Uneven rear tire wear related to suspension geometry wear
• Excess movement in the rear lower rearward track rod position
• Restoring OE-style alignment stability after suspension wear

Installation Notes and Tips

Verify the rear lower rearward position before ordering, especially on 2006-2008 Audi A6 models with VIN-specific notes. Inspect adjacent bushings, mounting points, and alignment settings during replacement. Mounting hardware is not included, and the arm is not adjustable, so a professional alignment is recommended after installation.

Quality Assurance

Delphi subjects its OE-style suspension components to temperature extremes below -40 degrees C and above 120 degrees C, along with extended salt-spray exposure testing. That validation supports fitment consistency and corrosion resistance for Audi A6, Audi A6 Quattro, and Audi S6 rear suspension service.
