Tool number: ST30901000
4. Place pinion front bearing inner cone in final drive housing.

6. Place drive pinion bearing spacer, pinion bearing adjustingwasher and drive in final drive housing.
7. Insert companion flange into drive pinion by tapping the com- panion flange with a soft hammer.
8. Tighten pinion nut to the specified torque.
The threaded portion of drive pinion and pinion nut should be
free from oil or grease. Tool number:ST38060002
9. Turn drive pinion in both directions several revolutions, and measure pinion bearing preload.Tool number: ST3127S000
Pinion bearing preload: 1.2 - 1.6 N ×m (12 - 16 kg-cm, 10 - 14 in-lb)
When pinion bearing preload is outside the specifications,
replace pinion bearing adjusting washer and spacer with a
different thickness.
10. Select side retainer adjusting washer. Refer to Adjustment.
11. Press-fit side bearing outer race into side retainer. Tool number:q

12. Place the differential case assembly in its housing.
13. Install side oil seal.
14. Place side retainer adjusting shims and O-ring on side retainer,and install them in final drive housing.Tool number: ST33720000
I Align arrows stamped on side retainer and final drive housing.
15. Measure ring gear-to-drive pinion backlash with a dial indicator. Ring gear-to-drive pinion backlash:0.13 - 0.18 mm (0.0051 - 0.0071 in)
I If 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.

16. Check total preload with Tool.
When checking preload, turn drive pinion in both directions
several times to set bearing rollers.
The total pinion bearing preload value with the differential case
assembly should be in accordance with the same value measured
without the differential case assembly. (See point 9.)
The relationship between both is:
Pinion bearing preload

12 1.2 13 - 18 1.3 - 1.8
13 1.3 14 - 19 1.4 - 1.9
14 1.4 15 - 20 1.5 - 2.0
15 1.5 16 - 21 1.6 - 2.1
16 1.6 17 - 22 1.7 - 2.2
17 1.7 18 - 23 1.8 - 2.3
Tool number: ST3127S000
Total preload:1.0 - 2.3 N ×m (10 - 23 kg-cm, 8.7 - 20.0 in-lb)
I If preload is too great, remove the same amount of shim from
each side.
I If 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.
17. Recheck ring gear-to-drive pinion backlash because increase or decrease in thickness of shims will cause change of ring
gear-to-pinion backlash.
18. Check runout of ring gear with a dial indicator. Runout limit:0.05 mm (0.0020 in)
I If backlash varies excessively in different places, the variance
may have resulted from foreign matter caught between the ring
gear and the differential case.
I If 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.

Pre-inspection
Before disassembling final drive, perform the following inspection.
ITotal preload
1) Turn drive pinion in both directions several times to seat bear- ing rollers correctly.
2) Check total preload with Tool. Total preload:1.5 - 2.9 N ×m (15 - 30 kg-cm, 13 - 26 in-lb)
Tool number: ST3127S000
I Ring gear to drive pinion backlash
Check backlash of ring gear with a dial indicator at several
points.
Ring gear-to-drive pinion backlash: 0.10 - 0.20 mm (0.0039 - 0.0079 in)
I Ring gear runout
Check runout of ring gear with a dial indicator.
Runout limit: 0.08 mm (0.0031 in)
I Tooth contact
Check tooth contact, referring to Adjustment.
I 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: 0.10 - 0.20 mm (0.0039 - 0.0079 in)
