7. Select the proper pinion height washer.
Drive pinion height adjusting washer:
Refer to SDS (PD-0, 53).
If you cannot ®nd the desired thickness of washer, use washer
with thickness closest to the calculated value.
Example (H233B):
Calculated value ... T = 3.32 mm
Used washer ... T = 3.33 mm
Tooth Contact
Gear tooth contact pattern check is necessary to verify correct
relationship between ring gear and drive pinion.
Hypoid gear sets which are not positioned properly in relation to
one another may be noisy, or have short life or both. With a pat-
tern check, the most desirable contact for low noise level and long
life can be assured.
1. Thoroughly clean ring gear and drive pinion teeth.
2. Sparingly apply a mixture of powdered ferric oxide and oil or
equivalent to 3 or 4 teeth of ring gear drive side.

Differential Case Ð 4-pinion type Ð
1. Measure clearance between side gear thrust washer and dif-
ferential case.
Clearance between side gear thrust washer
and differential case (A Ð B):
0.15 - 0.20 mm (0.0059 - 0.0079 in)
The clearance can be adjusted with side gear thrust washer.
Refer to SDS.
2. Apply oil to gear tooth surfaces and thrust surfaces and check
that they turn properly.
3. Install differential case LH and RH.
4. Place differential case on ring gear.
5. Apply locking sealer to ring gear bolts, and install them.
Tighten bolts in a criss-cross fashion, lightly tapping bolt head
with a hammer.
6. Press-®t side bearing inner races on differential case with Tool.

Differential Case Ð 2-pinion type Ð
1. Install side gears, pinion mate gears and thrust washers into
differential case.
2. Fit pinion mate shaft to differential case so that it meets lock pin
holes.
3. Adjust backlash between side gear and pinion mate gear by
selecting side gear thrust washer. Refer to SDS.
Backlash between side gear and pinion mate gear
(Clearance between side gear thrust washer and dif-
ferential case):
0.15 - 0.20 mm (0.0059 - 0.0079 in)
4. Install pinion mate shaft lock pin with a punch.
Make sure lock pin is ¯ush with case.
5. Apply gear oil to gear tooth surfaces and thrust surfaces and
make sure they turn properly.
6. Install differential case assembly on ring gear.
Tighten bolts in a criss-cross pattern, lightly tapping bolt head
with a hammer.

6. Install drive pinion bearing spacer, pinion bearing adjusting
shim and drive pinion in gear carrier.
7. Insert companion ¯ange into drive pinion by tapping the com-
panion ¯ange with a soft hammer.
8. Tighten pinion nut to the speci®ed torque.
The threaded portion of drive pinion and pinion nut should be
free from oil or grease.
Tool number: KV38104700
9. Turn drive pinion in both directions several times, and measure
pinion bearing preload.
Tool number: ST3127S000
Pinion bearing preload (with front oil seal):
1.4 - 1.7 Nzm (14 - 17 kg-cm, 12 - 15 in-lb)
If preload is out of speci®cation, adjust the thickness of spacer and
shim combination by replacing shim and spacer with thinner one.
+Start from the combination of thickest spacer and shim.
+Combine each spacer and shim thickness one by one until the
correct speci®cation are achieved.
Drive pinion bearing preload adjusting spacer and
shim:
Refer to SDS (PD-51).

10. Install differential case assembly with side bearing outer races
into gear carrier.
11. Position side bearing adjusters on gear carrier with threads
properly engaged; screw in adjusters lightly at this stage of
assembly.
Tool number:
ST32580000
12. Align mark on bearing cap with that on gear carrier and install
bearing cap on gear carrier.
+Do not tighten at this point to allow further tightening of side
bearing adjusters.
13. Tighten both right and left side bearing adjusters alternately and
measure ring gear backlash and total preload at the same time.
Adjust right and left side bearing adjusters by tightening them
alternately so that proper ring gear backlash and total preload
can be obtained.
Ring gear-to-drive pinion backlash:
0.15 - 0.20 mm (0.0059 - 0.0079 in)
+When checking preload, turn drive pinion in both direc-
tions several times to set bearing rollers.
