Keep your front suspension tight and your steering true with the Delphi control arm and ball joint assembly TC2952. It installs as a direct-fit replacement in the front right lower rearward position on the 2009-2017 BMW X3 and 2015-2018 BMW X4 — see the Buyer's Guide tab for engine-specific applications.
The control arm locates the wheel and pivots with suspension travel, while the integrated ball joint allows the steering and articulation motion the corner needs. Delphi applies its OE steering expertise to this aftermarket unit, using dimensional and material analysis for close compatibility with the original part.
- Tested to the extreme: withstands temperatures below -40°C and over 120°C, plus 720 hours of salt spray.
- Verified materials: 100% crack detection and ultrasonic flaw detection confirm the materials match OE specifications.
- Precision ball studs: machined to micron tolerances for durability and smooth joint operation.
- Robot-welded and protected: robot welding for consistent quality, with anti-corrosion protection for corrosion prevention and enhanced appearance.
Common signs of a worn control arm or ball joint include clunking or knocking over bumps, loose or wandering steering, and uneven tire wear; if a failed control arm or ball joint is the cause, this assembly replaces it.
