2002 NISSAN TERRANO Service Repair Manual

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
IAlign 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)
IIf 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
With differential case assembly Without differential case assembly
kg-cm N×m kg-cm N×m
11 1.1 12 - 17 1.2 - 1.7
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)
IIf preload is too great, remove the same amount of shim from
each side.
IIf 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)
IIf backlash varies excessively in different places, the variance
may have resulted from foreign matter caught between the ring
gear and the differential case.
IIf 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:
1.7 - 2.5 N×m (17 - 25 kg-cm, 15 - 22 in-lb)
Tool number:
ST3127S000
IRing gear to drive pinion backlash
Check backlash of ring gear with a dial indicator at several
points.
Ring gear-to-drive pinion backlash:
0.15 - 0.20 mm (0.0059 - 0.0079 in)
IRing gear runout
Check runout of ring gear with a dial indicator.
Runout limit:
0.08 mm (0.0031 in)
ITooth contact
Check tooth contact, referring to Adjustment.
ISide 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)

1. Mount final drive assembly on Tool.
Tool number:
ST06340000
2. Put match marks on one side bearing cap with paint or punch
to ensure that it is replaced in proper position during reassem-
bly.
Bearing caps are line-bored during manufacture and should
be put back in their original places.
3. Remove side lock fingers and side bearing caps.
4. Remove side bearing adjuster with Tool.
Tool number:
