Locate and support your front wheel with the Delphi control arm TC6248, a FRONT RIGHT UPPER control arm and ball joint assembly built as a direct-fit replacement for the 2005-2006 Ford Expedition and the 2005-2006 Lincoln Navigator. Delphi applies its OE steering and suspension expertise to the aftermarket, so this unit is engineered to match the original part's dimensions and function for the listed applications.
- OE-level validation: tested to extremes — down below -40°C and above 120°C, plus 720 hours of salt-spray exposure — with extensive dimensional and material analysis for close OE compatibility.
- 100% inspection: every control arm passes crack detection and ultrasonic flaw detection so materials match OE specifications.
- Precision ball stud: studs machined to micron tolerances for durable, smooth joint operation.
- Robot-welded construction: for consistent quality, with anti-corrosion protection applied for corrosion prevention and improved appearance.
The control arm positions the wheel and its integrated ball joint allows steering and suspension travel. If worn control-arm bushings or a failed ball joint are the cause of clunking, loose steering, or uneven tire wear, this Ford Expedition control arm replaces the original. It fits equally as a Lincoln Navigator control arm on the applications above. Diagnose the cause before replacing.
