Keep your Audi's front suspension precisely located and pivoting smoothly with the Delphi control arm TC2975. This control arm and ball joint assembly mounts in the front right upper position (forward and rearward), locating the wheel while its integrated ball joint lets the steering knuckle pivot through its travel. It's a direct-fit replacement for a range of Audi models — including the 2012-2018 Audi A6 and A6 Quattro, 2012-2018 A7 Quattro, 2009-2012 Q5, 2010-2013 S5, 2013-2018 S6 and S7 — plus the 2015-2020 Porsche Macan; see the Buyer's Guide tab for the full list and engine coverage.
- OE-level testing: Delphi applies its OE steering expertise to the aftermarket, testing to extremes — below -40°C, above 120°C, and 720 hours of salt spray — with dimensional and material analysis for close OE-to-aftermarket compatibility.
- Verified materials: each arm undergoes 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball stud: the ball studs are machined to micron tolerances for durable, smooth joint operation.
- Built consistent: robot welding delivers consistent quality, and anti-corrosion protection is applied to each part for corrosion prevention and improved appearance.
Signs this Audi A6 suspension arm may need replacing include clunking on acceleration, deceleration, or over bumps, uneven tire wear, and loose or wandering steering — diagnose the cause before replacing.
