Keep your BMW's front suspension precisely located with the Delphi control arm and ball joint assembly TC2227, a direct-fit replacement for the front left lower forward position on the 2007-2018 BMW X5 and 2008-2019 BMW X6. It locates the wheel, sets suspension geometry, and its integrated ball joint lets the steering knuckle pivot through travel — worn bushings or a loose joint can show up as clunking on acceleration or over bumps, wandering steering, or uneven tire wear.
Features:
- OE-level validation: tested to the extreme for OE performance — below -40°C and above 120°C, plus 720 hours of salt spray, with dimensional and material analysis for the closest OE-to-aftermarket compatibility.
- 100% flaw inspection: every arm receives crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball studs: the ball studs are machined to micron tolerances for durability and smooth joint operation.
- Robot-welded, corrosion-protected: robotic welding for consistent quality, with anti-corrosion protection applied to each part for corrosion prevention and enhanced appearance.
Delphi carries its OE steering expertise into the aftermarket, so if you've been checking Delphi control arm reviews before replacing a worn X5 control arm, this front left lower forward assembly is a direct-fit for the listed BMW applications.
