      Team rear axle

      Arrived on time. Wheel speed gear is not installed. Heat gear with a torch and have a tube that will Mach up with the gear diameter and long enough to stick above the axle. Hammer into place.

          Word on the Trail

          My favorite part is that you can put in your trucks make and model, and only shop parts that will fit that truck. Makes life so much easier.
