Keep your steering precise and the front suspension quiet and controlled with the Delphi ball joint TC3648, a front upper suspension ball joint that pivots the steering knuckle against the control arm while letting the wheel steer and the suspension move. It fits many vehicles, among them the 1997-2006 Jaguar XK8, 2000-2006 Jaguar XKR and 1998-2003 Jaguar Vanden Plas — see the Buyer's Guide tab for the full list.

Delphi carries its OE expertise into its aftermarket steering portfolio, testing to the extreme: parts withstand temperatures below -40°C and above 120°C and endure 720 hours of salt spray, with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.

  • Forged construction: made with high-quality forgings for increased strength and smooth operation.
  • Chloroprene rubber boot: improves durability and helps prevent premature failure.
  • Micron-tolerance machining: 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 front upper ball joint is behind your clunking over bumps, wandering steering, or uneven tire wear, this replaces it.
