Remove the stock mounting hardware at all 4 mounting points.
Lower front differential until you can insert the differential spacers. (We rec-
ommend doing one side at a time to keep the differential from becoming
cumbersome when inserting the differential spacers). The large spacer goes
toward the front of the truck and shorter spacer goes toward the rear of the
vehicle. Once the spacers are in place, install the new differential hard-
ware provided.
