Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC5479
Delphi Suspension Control Arm and Ball Joint Assembly P/N:TC5479
$103.99

Help keep steering precise and suspension travel quiet with the Delphi control arm and ball joint assembly, part number TC5479. This front right upper unit drops in as a direct-fit replacement for the 2003-2004 Ford Expedition and 2003-2004 Lincoln Navigator, locating the wheel and pivoting through its integrated ball joint so the wheel can steer and move over the road. It draws on Delphi's OE engineering, applied to their aftermarket steering portfolio.

Built and tested to OE standards:

  • Extreme validation: withstands temperatures below -40°C and over 120°C, with 720 hours of salt-spray exposure; dimensional and material analysis targets close OE-to-aftermarket compatibility.
  • Inspected material: 100% crack detection and ultrasonic flaw detection help ensure materials match OE specifications.
  • Precision stud: ball studs machined to micron tolerances for durability and smooth joint operation.
  • Consistent build: robot welding for repeatable quality, plus anti-corrosion protection applied to each part for corrosion prevention and improved appearance.

Worn control arm bushings or a loose ball joint can show up as clunking over bumps, wandering steering, or uneven tire wear. If a failed front right upper control arm is the cause, this assembly replaces it. See the Buyer's Guide tab for engine details.
