Tighten up your Audi's front end with the Delphi control arm TC2973, a front right upper control arm and ball joint assembly that locates the wheel, positions the suspension geometry, and pivots on an integrated ball joint. It's a direct-fit replacement for the listed applications, including the 2012-2014 and 2016-2018 Audi A6 Quattro, plus the Audi A6, A7 Quattro, S6, S7, A4 Allroad, Allroad, A5, A5 Quattro, Q5, RS7, S5 and the Porsche Macan — see the Buyer's Guide tab for the full year-by-year list.
- Tested to the extreme: validated below -40°C, above 120°C, and through 720 hours of salt spray, with dimensional and material analysis for OE-to-aftermarket compatibility.
- OE-matched materials: 100% crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball studs: machined to micron tolerances for durable, smooth joint operation.
- Built for consistency: robot-welded for repeatable quality, with anti-corrosion protection applied for corrosion prevention and appearance.
Clunking or knocking over bumps, loose or wandering steering, and uneven tire wear can be signs a control arm bushing or ball joint may be worn; if the arm is the cause, this assembly replaces it. Have the suspension inspected first to confirm the cause.
