2. Remove the tire and wheel assembly. Refer to Tire and Wheel Removal and Installation .
3. Remove the rear cover and gasket. Refer to Rear Axle Housing Cover and Gasket Replacement .
4. Remove the pinion shaft locking bolt.



5. On axles without a locking differential, remove the pinion shaft.



6. On axles with a locking differential, remove the shaft part way. Rotate the case until the pinion shaft touches the housing.



7. On axles with a locking differential, use a screwdriver, or a similar tool, in order to enter the differential case and rotate the lock (1) until the lock aligns with the thrust block (2).



8. Remove the brake drum.
9. Push the flange of the axle shaft in toward the differential.
10. Remove the C-lock from the button end of the axle shaft.

Important: Carefully insert the axle shaft in order to not damage the seal.

1. Install the axle shaft into the rear axle housing.
2. Slide the axle shaft into place allowing the splines to engage the differential side gear.
3. On axles without a locking differential, place the C-lock on the button end of the axle shaft.
4. On axles with a locking differential, keep the pinion shaft partially withdrawn.
5. Install the brake drum.



6. On axles with a locking differential, place the C-lock (1) on the axle shaft (3) so that the ends are flush with the thrust block (2).
7. Pull the shaft flange outward in order to seat the lock in the differential gear.



8. Align the hole in the pinion shaft with the bolt hole in the differential case.
