Detailed Description

Delphi applies OE-focused engineering to its aftermarket steering and suspension portfolio, and TC8348 reflects that approach with dimensional and material analysis aimed at proper fit and function. This rear left lower rearward control arm uses steel construction and rubber bushings to support suspension articulation while helping maintain alignment stability on Audi A6 allroad, Audi A6 Quattro, Audi Q7, Audi Q8, Audi SQ5, and related applications. This part cross-references 4M0 501 529 N and 80A 501 529 A for the same application.

What It Helps Address

• Rear suspension looseness or excess movement at the control arm
• Clunking or knocking from worn bushings
• Uneven tire wear related to rear alignment issues
• Steering or handling instability caused by worn suspension links
• Corrosion-related replacement needs on the rear suspension arm

Installation Notes and Tips

Replace the control arm in the correct rear left lower rearward position and verify all suspension fasteners are torqued to the vehicle manufacturer’s specifications. Because mounting hardware is not included, inspect existing hardware before installation and replace any worn or damaged fasteners as needed. A professional alignment is recommended after suspension work on compatible Audi A6 Quattro, Audi Q7, Audi Q8, and related models.

Quality Assurance

Delphi subjects its OE-style suspension components to extreme temperature and salt-spray testing, along with dimensional and material checks to support fitment consistency and durability. Part number TC8348 is built as a standard replacement control arm for the listed Audi applications.
