21. Remove the carrier assembly (1), bearing races (2), and shims (3).
Important: The ring gear bolts are not to be reused. Use new bolts during assembly.
22. Remove the bolts (3) and the ring gear (1) from the carrier (2).
23. Identify the lock pin location (1) within the differential case.
24. Drive the pinion shaft roll pin from the access hole (3) until the pinion shaft (2) can be removed from the differential case (1).
25. Remove the washers (1), pinion gears (2) and side gears (3) from the differential case.
26. Using J 44854 (3), J 22912-01 (2), and J 44855 (1), place the carrier into a press and press off the bearing.
27. Turn the carrier over, using the same; remove the right side differential bearing.
28. Using a punch, bend out the flat on both sides of the pinion nut.
29. Place J 44864 (1) over the pinion shaft. Turn the shaft to align the hex nut with the flat on the assembly holding fixture J 44869 (2).
30. Place J 44865 (1) and the breaker bar over the pinion splines. Remove the nut.
Important: The pinion nut is not reusable.
31. Remove J 44864 (1) and the nut.
