8. To remove the differential side gears and the differential pinion gears, rotate the differential side gears. The differential pinion gears will turn to
the opening of the differential case.
9. Remove the differential pinion gears and the differential pinion thrust washers behind the differential pinion gears.
10. Lift out the differential side gears and the differential side gear thrust washers.
ASSEMBLY
1. Place the differential case in a vise. Apply Premium Long-Life Grease XG-1-C or -K or equivalent meeting Ford specification ESA-M1C75-B to
new differential side gear thrust washers and to rear hubs and thrust face of the new differential side gears.
2. Apply grease to the new differential pinion thrust washers and the new differential pinion gears.
3. Assemble both differential side gears and differential side gear thrust washers. Hold in place with hand, then assemble the differential pinion gears
and differential side gear thrust washers to hold the differential side gears in place.
NOTE: An easy way to assemble the differential side gears and differential pinion gears is to have all parts lubricated with rear axle lubricant
WSP-M2C197-A or equivalent before assembly.
4. If necessary, use a drift to line up the holes with those of the differential case.
NOTE: Rotate the differential side gears until the holes of the differential side gear thrust washers and the differential pinion gears line up with
the holes of the differential case. If the differential pinion gears cannot be rotated by hand, install one of the axle shafts into the spline of the
differential side gear and use a pipe wrench to turn the axle shaft.
5. Assemble the differential pinion shaft and drive on the differential pinion shaft to remove the drift. Align the lock pin hole of the differential
pinion shaft with the lock pin hole of the differential case
6. Install a new differential pinion shaft lock pin after assembling the axle shafts.
