Detailed Description

Delphi TC3597 is a rear lower forward suspension control arm used on many Audi and Porsche platforms, including Audi A4, A6, A7, A8, Q5, S4, S5, SQ5, RS5, RS7, S6, S7, S8, allroad, and Porsche Macan. It is also referenced by OE number 8K0 501 529 L for the same application. If you are replacing a worn rear lower forward control arm on an Audi A4 Quattro, Audi Q5, or Porsche Macan, TC3597 provides a direct service solution built around OE fit and material standards.

This part number, TC3597, is intended for vehicles across model years 2009 through 2022, with fitment varying by chassis and suspension package. Confirm the exact year, model, and notes before ordering, especially for vehicles with off-road packages, air ride, or standard vehicle options.

What It Helps Address

• Clunking or knocking from the rear suspension
• Excessive play from a worn control arm bushing or joint
• Uneven rear tire wear caused by suspension looseness
• Imprecise rear suspension geometry after component wear
• Inspection failures related to worn suspension linkage

Installation Notes and Tips

Install TC3597 in the rear lower forward position only. Verify vehicle-specific notes before installation, since some Audi applications require matching suspension options such as off-road package, standard vehicle option, or air ride exclusions. After replacement, a wheel alignment is recommended to restore suspension geometry and tire wear characteristics.
