1. Press-fit front and rear bearing outer races with Tools.
Tool numbers:
VAST30611000
VBST30621000
VCST30613000
2. Select pinion height adjusting washer. Refer to ªADJUST-
MENTº of original Service Manual.
3. Install pinion height adjusting washer in drive pinion, and
press-fit rear bearing inner cone in it, with press and Tool.
Tool number: ST30901000
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. Place drive pinion bearing spacer, drive pinion bearing
adjusting washer and drive pinion in gear carrier.
7. Insert sensor rotor into companion flange with Tool.
Tool number: ST30720000
8. Install ABS sensor unit on gear carrier.
9. Insert companion flange into drive pinion by tapping the com-
panion flange with a soft hammer.
10. Tighten pinion nut to 127 N´m (13 kg-m, 94 ft-lb).
The threaded portion of drive pinion and pinion nut should
be free from oil or grease.

11. Turn drive pinion in both directions several revolutions and
measure pinion bearing preload.
Tool number: ST3127S000
Pinion bearing preload (With front oil seal):
1.1 - 1.4 N´m
(11 - 14 kg-cm, 9.5 - 12.2 in-lb)
Pinion bearing preload (Without front oil seal):
1.0 - 1.3 N´m
(10 - 13 kg-cm, 8.7 - 11.3 in-lb)
When pinion bearing preload is outside the specifications,
replace pinion bearing adjusting washer and spacer with a
different thickness.
12. Select side bearing adjusting washer.
Refer to ªADJUSTMENTº of original Service Manual.
13. Install differential case assembly with side bearing outer
races into gear carrier.
14. Insert left and right side bearing adjusting washers in place
between side bearing and carrier.
15. Drive in side bearing spacer with Tool.
Tool number: KV38100600
CAUTION:
Be aware that the spacer is installed in different locations on
different models. Refer to PD-2007.
16. Align mark on bearing cap with that on gear carrier and install
bearing cap on gear carrier.

17. Measure ring gear-to-drive pinion backlash with a dial indi-
cator.
Ring gear-to-drive pinion backlash:
0.13 - 0.18 mm
(0.0051 - 0.0071 in)
lIf backlash is too small, decrease thickness of right shim and
increase thickness of left shim by the same amount.
If backlash is too great, reverse the above procedure.
Never change the total amount of shims as it will change the
bearing preload.
18. Check total preload with Tool.
When checking preload, turn drive pinion in both directions
several times to seat bearing rollers correctly.
Total preload:
P
1+ [0.3 to 1.5 N´m (3 to 15 kg-cm, 2.6 to 13.0 in-
lb)]
P
1: Pinion bearing preload
Refer to SDS, PD-2014.
Tool number: ST3127S000
lIf preload is too great, remove the same amount of shim from
each side.
lIf preload is too small, add the same amount of shim to each
side.
Never add or remove a different number of shims for each
side as it will change ring gear-to-drive pinion backlash.
19. Recheck ring gear-to-drive pinion backlash because
increase or decrease in thickness of shims will cause change
of ring gear-to-pinion backlash.
20. Check runout of ring gear with a dial indicator.
Runout limit:
0.05 mm (0.0020 in)
lIf backlash varies excessively in different places, the vari-
ance may have resulted from foreign matter caught between
the ring gear and the differential case.
lIf the backlash varies greatly when the runout of the ring gear
is within a specified range, the hypoid gear set or differential
case should be replaced.
21. Check tooth contact.
Refer to ªADJUSTMENTº of original Service Manual.
22. Install rear cover and gasket.
