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 "Vehicles it fits" section for engine-level fitment.
