Pre-inspection
Before disassembling ®nal drive, perform the following inspection.
+Total preload
1) Turn drive pinion in both directions several times to set bearing
rollers.
2) Check total preload with Tool.
Tool number: ST3127S000
Total preload (with front oil seal):
Drive pinion bearing
New parts
1.7 - 2.5 Nzm (17 - 25 kg-cm, 15 - 22 in-lb)
Used parts
1.5 - 1.7 Nzm (15 - 17 kg-cm, 13 - 15 in-lb)
+Ring gear to drive pinion backlash
Check ring gear-to-drive pinion backlash with a dial indicator at
several points.
Ring gear-to-drive pinion backlash:
0.15 - 0.20 mm (0.0059 - 0.0079 in)
+Ring gear runout
Check runout of ring gear with a dial indicator.
Runout limit:
0.08 mm (0.0031 in)
+Tooth contact
Check tooth contact. Refer to ADJUSTMENT (PD-27).
+Side gear to pinion mate gear backlash
Measure clearance between side gear thrust washer and dif-
ferential case with a feeler gauge.
Clearance between side gear thrust washer and differ-
ential case:
0.15 - 0.20 mm (0.0059 - 0.0079 in)

Be careful to keep the side bearing outer races together with
their respective inner cones Ð do not mix them up.
6. Loosen drive pinion nut with Tool.
Tool number: KV38104700
7. Remove companion ¯ange with puller.
8. Take out drive pinion together with pinion rear bearing inner
cone, drive pinion bearing spacer and pinion bearing adjusting
shim with soft hammer.
9. Remove front oil seal and pinion front bearing inner cone.
10. Remove pinion bearing outer races with a brass drift.

CAUTION:
Do not damage roller side face.
2. Select drive pinion height adjusting washer. Refer to ADJUST-
MENT (PD-27).
3. Install drive pinion height adjusting washer in drive pinion, and
press-®t pinion rear bearing inner cone in it, with press and
Tool.
Tool number: ST30911000
4. Place pinion front bearing inner cone in gear carrier.
5. Apply multi-purpose grease to cavity at sealing lips of oil seal.
Install front oil seal.

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.
