F 250 4WD Super Duty V10-6.8L VIN S (2001)
3. NOTE: The best way to assemble the differential side gears and the differential pinion gears is to lubricate all parts with the specified rear axle
lubricant.
Lubricate and assemble both differential side gears and differential side gear thrust washers. Hold them in place. Then, lubricate and assemble the
differential pinion gears and the differential pinion gear thrust washers to hold the differential side gears in place.
4. NOTE: Rotate the differential side gears until the holes of the differential pinion gear thrust washers and the differential pinion gears line up with
the holes of the differential case. If the differential pinion gears will not rotate 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.
Using a drift, line up the holes with those of the differential case.
5. Assemble the differential pinion shaft and drive on the differential pinion shaft to remove the drift. Align the lock pin hole in the differential pinion
shaft with the lock pin hole in the differential case.
6. Assemble the differential pinion shaft lock pin. Peen the metal of the differential case over the differential pinion shaft lock pin in two places, 180
degrees apart, to lock it in place. Note the location of the slot in the differential pinion shaft lock pin and peen it 90 degrees apart.
