10. Tighten the bolts and torque them to 70 to
90 ft. lbs. (Figure 92).
NOTE: This is the root-to-root reading. Write
this number under the total travel number. With
the total travel and the root-to-root reading, the
starting differential spacers can be determined.
The root-to-root reading is always the flange side
differential spacer. The remainder is always the
button side spacer. To calculate this number,
subtract the root-to-root travel from the total
travel taken earlier. Using the previous examples:
.340" - .180" = .160".
The flange side spacer is .180" and the button side
spacer is .160". With these starting numbers, there
should be zero backlash and zero differential
preload.

15. Measure the spacers before installing them in
the carrier. Write down the numbers for later
reference.
16. Drive the bearing onto the button side of the
hub using a Miller tool C-4340 (Figure 94).
13. Set the dial indicator to zero. Slide the case to
the right so that the root of the ring gear
tooth meets with the root of the pinion tooth.
14. Repeat this procedure one or two times to be
sure the reading is correct, .180" for example.
11. Put the dummy bearing back on the case and
slide it into the differential bores. Keep the
flange side of the case to the left.
Do not drop the case and ring
gear into the carrier, because it could damage
the ring gear or pinion.
12. Attach a dial indicator to the carrier again, and
put the tip of the indicator on thetop edge of
the ring gear tooth (Figure 93).
