Keep your front suspension geometry in check with the Delphi control arm and ball joint TC971 — a direct-fit front right lower forward replacement for the 1995 and 1997-2001 BMW 740I, the 1995-2001 BMW 740IL, and the 1995-2001 BMW 750IL (see the Buyer's Guide tab for engine details). This assembly locates the wheel and lets the suspension move through its travel while the integrated ball joint allows steering and articulation.
- OE-derived engineering: Delphi applies its OE steering expertise to the aftermarket, testing parts below -40°C and above 120°C and through 720 hours of salt spray, with dimensional and material analysis for OE-matched compatibility.
- Verified materials: 100% crack detection and ultrasonic flaw detection confirm the materials match OE specifications.
- Precision ball studs: the ball studs are machined to micron tolerances for durability and smooth joint operation.
- Built to endure: robot welding delivers consistent quality, and anti-corrosion protection is applied to each part for corrosion prevention and improved appearance.
Signs the original may need replacing include clunking over bumps, steering wander, uneven tire wear, and looseness or play in the ball joint. If a worn control arm or ball joint is the cause, this Delphi assembly replaces it.
