FIGURE 27
If the number of shims that have been used between the
pinion shaft front bearing and spacer, do not give the recommended
resistance torque, shims will have to be added
or removed.
10. Insert cotter pin through nut and shaft and secure.
DIFFERENTIAL
1. Place differential case assembly in "V" blocks to check
side run out, using dial indicator KMO-30. Runout in
excess of .002" indicates a sprung differential case and
should be replaced.

5. Heat ring gear in hot water to 200° and Install on differential
case flange, tightening bolts to 50 foot pounds torque.
6. Two differential cases are used; one for the 3.58 ratio axle
and the other for the 4.1 and 4.55 ratio axles. These cases
are the same except for the machining dimensions shown.
The 3.58 ratio case may be identified by the flange groove.
2. Place differential side gears and thrust washers in right
and left hand case respectively.
NOTE: Thrust washers .091" thick are used in production
and .095" washers are available for service.
3. Assemble differential pinions, spacer and thrust washers
on the differential pinion shaft, and place in the left hand
half of the differential case, lining up the hole in the
shaft, with the pin in the case.
4. Replace bolts and lock washers that hold right and left
hand case together, being sure that the machining marks
are in alignment and tighten securely.
