Help keep your BMW's front-left wheel located and its steering connected with the Delphi control arm and ball joint assembly, MPN TC804 — a direct-fit replacement for the listed BMW models. It fits many BMW models, among them the 1989-1995 BMW 525i, 1994-1995 BMW 530i and 1994-1995 BMW 540i. The arm locates the front-left wheel and links it to the chassis while the integrated ball joint lets the suspension and steering move through their travel.

  • Tested to the extreme: validated for OE performance from below -40°C to over 120°C, with 720 hours of salt-spray exposure and 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: machined to micron tolerances for durability and smooth joint operation.
  • Robot-welded & protected: robotic welding for consistent quality, plus anti-corrosion protection for corrosion prevention and enhanced appearance.

Clunking over the front-left corner, loose or wandering steering, and uneven tire wear can be signs a worn control arm or ball joint may need replacing.

See the Buyer's Guide tab for the full list of applications and engine details.
