Delphi Suspension Ball Joint P/N:TC1621
Keep your steering tight and your suspension properly located with the Delphi ball joint TC1789, a direct-fit front lower replacement for the 1998-2004 Nissan Frontier and 2000-2004 Nissan Xterra. This pivoting joint connects the front lower control arm to the steering knuckle, allowing the wheel to steer and the suspension to travel while locating it against road loads. If a worn ball joint is behind clunking over bumps, loose steering, or uneven tire wear, this replaces it. See the Buyer's Guide tab for engine-level fitment.
Built on Delphi's OE safety technology, these parts are tested to the extreme for OE performance — withstanding temperatures below -40°C and over 120°C and enduring 720 hours of salt spray — with extensive dimensional and material analysis for close OE-to-aftermarket compatibility.
Front ball joints install as left/right pairs; inspect and service both sides as directed by the service procedure. Consult the vehicle service information for the correct fasteners and whether they may be reused.
