3. Using suitable drift, remove roll pin retaining cross pin, then drive out cross pin with hammer and suitable drift, Fig. 18.
4. Position step plate into bottom side gear and lubricate centering hole of step plate.
5. Position gear rotating tool into top side gear.
6. Lubricate threads of forcing screw and thread screw into gear rotating tool, guiding forcing screw into step plate.
7. Tighten forcing screw securely, then, using a piece of .030 inch shim or gauge stock, push out differential spherical washers.
8. Loosen forcing screw momentarily, then tighten forcing screw until a very slight movement of the differential pinion gears is seen.
9. Slide pawl of gear rotating tool between two side gear teeth and pull handle so top side gear rotates, rotating differential pinion gears. Remove differential pinion gears through large openings in case. When attempting to rotate side gear, it may be necessary to tighten or loosen forcing screw to permit gear movement.
10. Manually hold top side gear and clutch pack in case and remove forcing screw, then the gear rotating tool.
11. Remove top side gear and clutch pack, keeping plates and discs in exact order.
12. Turn case so that ring gear side faces up, easing step plate, side gear, and clutch pack out of case.
13. Remove retainer clips from clutch packs, keeping discs and plates in exact order.
