Differential Assembly

Inspection

To establish a starting point before disassembly, inspect
the following:

Ring gear backlash

Total bearing preload

Gear tooth contact

NOTE:

Be sure the differential is at room temperature before
inspecting.
Record the results of the preliminary inspections.

This information will be helpful during reassembly.

Ring gear backlash

1. Remove the oil filler plug and the oil seal.

OIL SEAL

Replace.

3. Align the differential gear inspection hole with the

oil filler plug hole.

4. Measure the backlash of the ring gear on the differ-

ential carrier using the special tools as shown. After

measuring, remove the dial gauge and turn the dif-

ferential carrier one full turn, then remeasure the

backlash.

Standard: 0.06 - 0.14 mm (0.002 - 0.006 in)

The difference between the two measurements taken

must not exceed 0.06 mm (0.002 in).

Total bearing preload

5. Remove the differential case cover and the differen-

tial carrier.

NOTE: Loosen the bolts in a crisscross pattern, in

several steps.

Use a dial-type torque wrench on the drive pinion to
measure the drive pinion bearing preload (Tp).

Standard: 1.42 - 1.91 N-m
(14.5 - 19.5 kgf-cm, 12.6 - 16.9 Ibf-in)

7. Reinstall the differential carrier and the differential

case cover, then measure the total bearing preload.
The total bearing preload should exceed the drive

pinion bearing preload (Tp) by:

Standard:
0.94 - 1.07 N-m (9.6 - 10.9 kgf-cm, 8.33 - 9.46 Ibf-in)

Example:

Total bearing preload (from step 7)

- Tp (from step 6)

Gear tooth contact

8. Remove the differential case cover and differential

carrier. Clean and paint the ring gear teeth lightly and
evenly with Prussian Blue (on both sides of each
tooth).

9. Reinstall the differential carrier and the differential

case cover, then torque the bolts in a crisscross pat-

tern in several steps.

10. Install the special tool as shown, then rotate the

drive pinion in both directions so that the ring gear
rotate one full turn in both directions. During this
operation resistance should be applied to the ring
gear.

DIFFERENTIAL
CASE COVER

Remove the bearing outer race and the 79.5 mm

thrust shim(s) from the differential case cover by heat-

ing the differential case cover to about 212°F (100°C).

NOTE:

Do not heat the differential case cover in excess
of 212°F (100°C).
If the bearing outer race was removed by heat-
ing, allow the differential case cover to cool to
room temperature.
Replace the tapered roller bearing with a new
one whenever the bearing outer race is replaced.
