Keep the front wheel firmly located and the steering responsive with the Delphi control arm and ball joint assembly TC2523, a front left lower unit built with Delphi's OE safety technology. It's a direct-fit replacement for the 1999-2003 Mazda Protege and the 2002-2003 Mazda Protege5 (see the Buyer's Guide tab for engine-level fitment). The control arm locates the wheel while the integrated ball joint lets the knuckle pivot for steering and suspension travel; if a worn Mazda Protege control arm is the cause of loose steering, uneven tire wear, or noise over bumps, this replaces it.
- Tested to the extreme: withstands temperatures below -40°C and over 120°C plus 720 hours of salt-spray exposure for OE-level performance.
- Verified materials: 100% crack detection and ultrasonic flaw detection confirm the material matches OE specifications.
- Precision ball stud: ball studs machined to micron tolerances for durability and smooth joint operation.
- Built for consistency: robot-welded construction, with anti-corrosion protection applied to each part for corrosion prevention and enhanced appearance.
Delphi's dimensional and material analysis targets close compatibility between the OE and aftermarket part.
