2006 NISSAN PATROL Service Manual

Removal and Installation
+Put matchmarks on ¯anges and separate propeller shaft from
®nal drive.
CAUTION:
When installing the propeller shaft, make sure it is facing the
correct direction. Each model is different.
Inspection
+Inspect propeller shaft runout. If runout exceeds speci®cations,
replace propeller shaft assembly.
Runout limit: 0.6 mm (0.024 in)
+Inspect journal axial play.
If the play exceeds speci®cations, replace propeller shaft
assembly.
Journal axial play:
0.02 mm (0.0008 in) or less
+Check ¯ange yoke and sleeve yoke for damage or wear.
Replace if necessary.
Disassembly
JOURNAL
1. Put matchmarks on shaft and ¯ange or yoke.

2. Remove snap ring.
3. Remove pushed out journal bearing by lightly tapping yoke with
a hammer, taking care not to damage journal and yoke hole.
4. Remove bearing at opposite side in above operation.
Put marks on disassembled parts so that they can be rein-
stalled in their original positions from which they were
removed.
Assembly
JOURNAL
1. Assemble journal bearing. Apply recommended multi-purpose
grease on bearing inner surface.
When assembling, be careful that needle bearing does not fall
down.
2. Select snap ring that will provide speci®ed play in axial direc-
tion of journal, and install them. (Refer to SDS.)
Select snap rings with a difference in thickness at both sides
within 0.06 mm (0.0024 in).

3. Adjust thrust clearance between bearing and snap ring to zero
by tapping yoke.
4. Check to see that journal moves smoothly and check for axial
play.
Axial play: 0.02 mm (0.0008 in) or less

Removal
+Remove propeller shaft.
+Remove drive shaft. Refer to FA section (``FRONT AXLE Ð
Knuckle Flange'').
+Remove axle shaft.
Refer to RA section (``REAR AXLE'').
+Remove front and rear ®nal drive mounting bolts.
CAUTION:
+Be careful not to damage spline, sleeve yoke and front oil
seal when removing propeller shaft.
+Before removing the ®nal drive assembly or rear axle
assembly, disconnect the ABS sensor harness connector
from the assembly and move it away from the ®nal drive/
rear axle assembly area. Failure to do so may result in the
sensor wires being damaged and the sensor becoming
inoperative.
Installation
+Fill ®nal drive with recommended gear oil.
+Pay attention to the direction of gasket.

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)
