Assembling Input Shaft
1. Place the pinion housing in a press and install the
input shaft bearing. Secure the bearing with the
existing snap ring making sure the sharp edge of the
snap ring faces to the outside.
2. Install the input shaft seal making sure it is fully
seated in the edge of the housing.
3. Lubricate the input shaft with High-Performance #2
Molybdenum Disulphide Grease packing the boot
ribs and splines; then assemble allowing excess
grease to freely escape. Slight pressure on the boot
will be present during assembly. Secure with new
clamps.

NOTE: Any time drive splines are separated, clean
all splines with parts-cleaning solvent and dry with
compressed air; then lubricate with recommended
grease.
4. Install the input shaft into the pinion housing; then
secure the bearing with a circlip.
5. Place the pinion housing with new gasket onto the
differential housing; then secure with existing cap
screws. Tighten to 23 ft-lb.
