NISSAN PICK-UP 1998 Repair Manual

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 may be
noisy, or have short life or both. With a pattern 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.
3. Hold companion flange steady and rotate the ring gear in
both directions.

Differential Case
1. Measure clearance between side gear thrust washer and
differential case.
Clearance between side gear thrust washer
and differential case (A þ B):
Less than 0.15 mm (0.0059 in)
The clearance can be adjusted with side gear thrust washer.
Refer to SDS, PD-80.
2. Apply gear oil to gear tooth surfaces and thrust surfaces and
check to see they turn properly.
3. Install differential case LH and RH.
4. Install differential case on ring gear.
5. Place differential case on ring gear.
6. Apply locking agent [Locktite (stud lock) or equivalent] to ring
gear bolts, and install them.
Tighten bolts in a criss-cross fashion, lightly tapping bolt
head with a hammer.
7. Press-fit side bearing inner cones on differential case with
Tool.

2. Select drive pinion height adjusting washer. Refer to
``ADJUSTMENT'', PD-67.
3. Install drive pinion adjusting washer in drive pinion, and
press-fit pinion 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. Install drive pinion bearing spacer, pinion bearing adjusting
shim and drive pinion in gear carrier.
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: KV38104700
9. Turn drive pinion in both directions several times, and mea-
sure pinion bearing preload.
Tool number: ST3127S000
Pinion bearing preload (With front oil seal):
1.4 - 1.7 N´m (14 - 17 kg-cm, 12 - 15 in-lb)
Pinion bearing preload (Without front oil seal):
1.2 - 1.5 N´m (12 - 15 kg-cm, 10 - 13 in-lb)
If preload is out of specification, adjust the thickness of spacer
and shim combination by replacing shim and spacer with thinner
one.
lStart from the combination of thickest spacer and shim.
lCombine each spacer and shim thickness one by one until
the correct specification is achieved.
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.

12. Align mark on bearing cap with that on gear carrier and install
bearing cap on gear carrier.
lDo 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:
0.13 - 0.18 mm (0.0051 - 0.0071 in)
lWhen checking preload, turn drive pinion in both direc-
tions several times to set bearing rollers.
Tool number: ST3127S000
Total preload (With front oil seal):
Drive pinion bearing
New: 1.5 - 1.7 N´m (15 - 17 kg-cm, 13 - 15 in-lb)
Old: 1.7 - 2.5 N´m (17 - 25 kg-cm, 15 - 22 in-lb)
14. Tighten side bearing cap bolts.
15. Install side lock finger in place to prevent rotation during
operation.
16. Check runout of ring gear with a dial indicator.
Runout limit: 0.08 mm (0.0031 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.
17. Check tooth contact. Refer to ``ADJUSTMENT'', PD-70.
