2. Install cam gear assembly along with shim in flange end of case, Fig. 8. If cam gear has been replaced, perform shim selection procedure prior to installation.
3. Install four guide clips on assembled side gear clutch pack using grease to retain clips.
4. Install side gear assembly in case along with shim. If side gear has been replaced, perform shim selection procedure prior to installation.
5. Lock axle shaft in vise with sufficient portion of spline protruding from vise to engage side gear, then mount case assembly on axle and engage axle with side gear.
6. Install thrust washers on back of differential pinions using grease to adhere washers.
7. Install one pinion assembly through small case opening while simultaneously installing remaining pinion and thrust block through large opening.
8. Rotate assembly approximately 90° to position open side of thrust block toward small opening in case and pinions in proper installed position. If side gears and/or thrust block have been replaced, refer to Thrust Block Selection Procedure to ensure proper assembly clearances. Refer to Thrust Block Selection. Thrust Block Selection
9. Insert pinion shaft ensuring that pinion thrust washers are properly positioned, then install new lock screw and torque screw to 20 ft. lbs.

Fig. 11 Governor & Latching Bracket Installation.:

10. Insert governor assembly and latching bracket into case, Fig. 11, positioning straight end of latching bracket spring over and to the outside of the engagement shaft to preload bracket against governor.
11. Press governor assembly bushing into case to a depth which will allow .004-0.020 inch shaft endplay.
12. Press latching bracket bushing into case to a depth which will provide zero to 0.003 inch shaft endplay.
