Keep your BMW's front suspension tight and controlled with the Delphi control arm and ball joint assembly, part number TC1750. This front right lower forward unit installs as a direct-fit replacement on many vehicles, among them the 2008-2012 BMW 128i and 2007-2012 BMW 328i — see the Buyer's Guide tab for the full list of covered applications.

  • OE-grade validation: tested to the extreme for OE performance — parts withstand below -40°C and over 120°C and endure 720 hours of salt spray, with extensive dimensional and material analysis for OE-to-aftermarket compatibility.
  • 100% inspected: every arm undergoes crack detection and ultrasonic flaw detection so materials match OE specifications.
  • Precision ball stud: ball studs are machined to micron tolerances for durability and smooth joint operation.
  • Robot-welded & protected: robotic welding delivers consistent quality, and anti-corrosion protection is applied to each part for corrosion prevention and enhanced aesthetics.

The control arm locates the wheel while the integrated ball joint allows steering and suspension travel. A worn control arm or ball joint can produce clunking over bumps, loose or wandering steering, and uneven tire wear; if a failed lower control arm or ball joint is the cause, this assembly replaces it. Diagnose the source of the symptom before replacing.
