Common Repair Uses

• Clunking or looseness from the front right lower suspension

• Suspension play during braking or cornering
• Inspection failure due to excessive joint movement
• Restoration of proper front-end geometry on Audi Cabriolet, Audi 90, and Audi Coupe Quattro models

Installation Notes and Tips

Verify the front right lower position and confirm chassis-specific notes before ordering, especially for 1990 Audi Coupe Quattro models with chassis number 8BL006000 and earlier. Inspect the surrounding control arm and mounting points for wear before installation. Because this is a bolt-on, threaded-stud assembly, proper torque and alignment checks after installation are recommended.

Quality Assurance

Delphi uses OE-oriented testing and material validation for its aftermarket steering and suspension portfolio. TC507 is evaluated for temperature resistance and corrosion exposure to support consistent service performance in the specified Audi fitments.
