Installation Notes and Tips

Verify vehicle year, model, and front upper position before ordering. This part is listed for 1998-2004 Nissan Frontier, 2000-2004 Nissan Xterra, and 2009-2010 Nissan Pickup. Because it is a press-in style ball joint, proper suspension service tools are recommended for removal and installation. Confirm the tapered stud, cotter pin hole, and castle nut alignment during assembly, and inspect related control arm and steering components at the same time.
