press fit. Put the assembly in a press with the ring
gear facing upward. Make certain that the ring gear
is flush and square to the differential case before
pressing. Press until ring gear bottoms out on the
case.
IMPORTANT:
DO NOT use the cap screws to draw the ring gear into place.
Only use a press.

IMPORTANT:
When pressing differential case bearing cones, note that the
bearing is beyond flush with the top of the case. The cone

sleeve that only contacts the inner race of the cone. A used
bearing race would be a suitable tool. This tool should have a
slit cut if the ID is the same as the bearing boss OD.
