Differential Case Assembly

Coat components with specified axle lubricant during assembly. If components are reused, they should be installed in original position.
1. Install 6 guide clips on ears of cam gear disc pack, using grease to retain clips.
2. Install cam gear assembly along with selected shim into right case half. If cam gear thrust ring was replaced, measure length of assembly from front face of cam gear to rear face of thrust ring, including shim. Select a shim that will provide a measurement as close to measurement made during disassembly as possible.
3. Install selected right side thrust block on cam gear face with button side of block facing up. If cam or side gears or thrust block was replaced, select thrust block thickness. Refer to Thrust Block Selection.
Improper thrust block clearance will result in differential malfunction.
4. Assemble differential pinions and thrust washers on yoke, index yoke to proper position, then install yoke in right side of case.
5. Ensure that yoke is centered over thrust block button and seat yoke in housing by tapping lightly with hammer.
6. Install left side thrust block, ensuring that thrust block button is seated in yoke. Ensure that thrust block is of proper thickness. Refer to Thrust Block Selection. Thrust Block Selection

7. Install governor and latching bracket in respective positions, Fig. 2, and position straight end of latching bracket spring over and to the outside of governor shaft to preload bracket against governor.
8. Install 6 guide clips on ears of side gear disc pack using grease to retain clips.
9. Install selected shim in left case half.
10. Carefully remove disc pack from side gear and lower assembly into right case half, ensuring that guide clips are properly positioned.
11. Insert side gear through disc pack into left case half, rotating gear as needed to align splines.
12. Hold side gear into case, then lower left case assembly onto right case half, ensuring that bores for governor and latching bracket shafts are properly aligned.
13. Invert assembly taking care not to dislodge internal components, then install 3 retaining screws.
14. Mount axle shaft in vise with spline protruding enough to engage side gear.
15. Install case assembly over axle shaft and rotate case to check operation. Assembly should rotate smoothly, without binding or locking-up.
16. Install ring gear and side bearings as outlined for standard differential. Refer to Corporate - Standard. Corporate - Standard
