Bring back precise steering and quiet, controlled ride with the Delphi control arm and ball joint assembly (TC3445), a front right lower rearward suspension arm with an integrated ball joint. It installs as a direct-fit replacement on the 2010-2015 Audi A4, 2010-2011, 2013-2015 and 2017 Audi Q5, 2010-2017 Audi S5, and 2015-2021 Porsche Macan, plus more Audi models — see the Buyer's Guide tab for the full list and engine coverage.
- OE-engineered validation: built with Delphi's OE expertise and tested to the extreme — components withstand below -40°C and over 120°C and endure 720 hours of salt spray, with dimensional and material analysis for OE-to-aftermarket compatibility.
- 100% inspected: every control arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball stud: the ball stud is machined to micron tolerances for durability and smooth joint operation.
- Robot-welded & protected: robotic welding for consistent quality, with anti-corrosion protection applied to each part for corrosion prevention and enhanced appearance.
This control arm locates the wheel and, through its ball joint, allows the steering and suspension to move together. Worn signs include clunking on bumps or turns, loose or wandering steering, and uneven tire wear. Sold individually; replace the matching side as directed by the service procedure.
