Restore precise wheel location and quiet handling with the Delphi control arm and ball joint assembly TC7777 — a Delphi control arm that pivots the suspension, positions the wheel, and lets the ball joint articulate through steering and travel. It fits the front right upper rearward position on the 2018-2022 Audi Q5, 2017-2022 Audi Q7, 2019-2022 Audi A6 Quattro, 2019-2022 Audi Q8, and 2019-2022 Porsche Cayenne, among 22 applications — see the Buyer's Guide tab for the full list and engine details.
- Tested to OE performance: validated below -40°C and above 120°C, exposed to 720 hours of salt spray, with dimensional and material analysis for OE compatibility.
- 100% inspected: every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball stud: machined to micron tolerances for smooth joint operation and durability.
- Robot-welded for consistent quality, with anti-corrosion protection applied to each part for corrosion prevention and improved appearance.
Clunking over the front suspension, loose or wandering steering, or uneven tire wear can be signs the original arm or ball joint may need replacing; if a worn assembly is the cause, this replaces it. Inspect both sides and follow the vehicle service procedure for alignment and fasteners after installation.
