Tighten up worn rear suspension with the Delphi control arm (P/N TC3090), a rear right upper arm that locates the wheel and lets the suspension travel while the integral ball stud pivots with the knuckle. It's a direct-fit replacement for the 2012-2018 Audi A6, 2012-2018 Audi A6 Quattro, and the 2015-2022 Porsche Macan, and also fits many more Audi applications including the A4, A5, A7 Quattro, A8 Quattro, Q5, S4, S5, S6, S7, S8, SQ5, RS5 and RS7 — see the Buyer's Guide tab for the full list of years and models.
- Tested to the extreme: validated below -40°C and above 120°C, exposed to 720 hours of salt spray, with dimensional and material analysis for close OE compatibility.
- Inspected 100%: crack detection and ultrasonic flaw detection confirm the material matches OE specifications.
- Robot-welded for consistent quality, with ball studs machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection applied to each part for corrosion prevention and improved appearance.
If a worn arm or ball joint is behind clunking over bumps, loose steering, or uneven tire wear, this replaces it to help restore proper stability and control. Delphi applies its OE steering expertise to this aftermarket portfolio.
