6. Install the nut in the upper differential side gear. Hold the nut in position while installing the hex screw. Tighten the hex-head screw until contact is
made with the Step Plate.
7. Insert a suitable dowel bar in the hole of the nut. Tighten the forcing screw to force the differential side gear away from the differential pinion
gears. The dowel bar is used to keep the nut from turning when the forcing screw is tightened.
8. WARNING: Keep fingers/hands away from pinion gears when rotating the differential case with the differential rotating tool.
Note: Differential pinion thrust washers cannot be removed independently of the differential pinion gears and so must be removed simultaneously
with the differential pinion gears.
Insert the special tool in the pinion shaft bore, and turn the differential case to "walk" the differential pinion gears and differential pinion thrust
washers out to the differential case windows.
