Keep your BMW's front end tracking straight with the Delphi control arm and ball joint assembly, MPN TC2228. This is the front right lower forward unit, dropping in as a direct-fit replacement for the 2007-2018 BMW X5 and 2008-2019 BMW X6 (see the Buyer's Guide tab for engine-level fitment). It combines the control arm and its integrated ball joint in a single assembly that helps locate the wheel and lets the suspension move through its travel — worn bushings or a loose ball stud can bring on clunking, wandering steering, and uneven tire wear.
- OE-derived engineering: built on Delphi's OE safety technology, with dimensional and material analysis for close compatibility to the original part.
- Tested to the extreme: validated below -40°C and above 120°C and exposed to 720 hours of salt spray.
- Quality verified: 100% crack detection and ultrasonic flaw detection confirm materials meet OE specifications; robot welding for consistent build.
- Precision ball stud: studs machined to micron tolerances for durability and smooth joint operation, with anti-corrosion protection applied to each part.
Suspension parts wear as a pair, so inspect the opposite side and replace both if needed for balanced handling.
