Delphi Suspension Ball Joint P/N:TC4165
Delphi Suspension Ball Joint P/N:TC4165
$57.99

Keep the rear suspension tight and steering predictable with the DELPHI ball joint TC4165, a rear right lower joint that pivots the control arm against the knuckle so the wheel can travel and turn smoothly. It fits the 2001-2008 Ford Escape and 2005-2008 Mercury Mariner — see the Buyer's Guide tab for engine-level applications.

Delphi applies its OE expertise to its aftermarket portfolio, testing to extremes for OE-level performance: parts endure temperatures below -40°C and above 120°C plus 720 hours of salt spray, with dimensional and material analysis for close OE-to-aftermarket compatibility.

  • Forged strength: high-quality forgings for increased strength and smooth operation.
  • Chloroprene boot: a chloroprene rubber boot improves durability and helps prevent premature failure.
  • Micron tolerances: machined to micron tolerances for durability and smooth joint operation.
  • Anti-corrosion protection: applied to each part for corrosion prevention and enhanced appearance.

If a worn rear right lower ball joint is behind clunking over bumps, loose steering, or uneven tire wear, this replaces it. Wondering about Ford Escape ball joint replacement cost — inspect the mating parts and torque to spec during install.
