Keep your BMW's rear suspension located and planted with the Delphi control arm TC2232, a rear lower control arm that carries Delphi's OE safety technology into the aftermarket. It's a direct-fit replacement across a wide range of 3 Series and related models — including the 1994-1999 and 2001-2006 BMW M3, the 2004-2010 BMW X3, and the 2003-2011 BMW Z4 — plus 318i, 318is, 320i, 323Ci, 323i, 323is, 325Ci, 325i, 325is, 325xi, 328Ci, 328i, 328is, 330Ci, 330i and 330xi. See the Buyer's Guide tab for the full list of applications and years.
Delphi tests to the extreme for OE performance: the part withstands temperatures below -40°C and over 120°C and endures 720 hours of salt spray, while extensive dimensional and material analysis targets close compatibility between the OE and aftermarket part.
- Verified integrity: 100% crack detection and ultrasonic flaw detection help ensure materials match OE specifications.
- Consistent build: robot welding for repeatable performance and quality.
- Precise joint: ball studs machined to micron tolerances for durability and smooth joint operation.
- Anti-corrosion protection: applied to each part for corrosion prevention and enhanced aesthetics.
A worn control arm can cause clunking over bumps, vibration, wandering steering and uneven tire wear; if the original arm or its ball joint is the cause, this replaces it.
