1998 NISSAN PATROL Drive shaft

Ring Gear and Drive Pinion
Check gear teeth for scoring, cracking or chipping. If any damaged
part is evident, replace ring gear and drive pinion as a set (hypoid
gear set).
Differential Case Assembly
Check mating surfaces of differential case, side gears, pinion mate
gears, pinion mate shaft, thrust block and thrust washers.
Bearing
1. Thoroughly clean bearing.
2. Check bearings for wear, scratches, pitting or ¯aking.
Check tapered roller bearing for smooth rotation. If damaged,
replace outer race and inner cone as a set.

To avoid confusion while calculating bearing shims, it is absolutely
necessary to stay with the metric system. If you measure anything
in inches,the results must be converted to the metric system.
Drive Pinion Height
1. First prepare Tools for pinion height adjustment.
:
V1Height gauge (ST31251000)
V2Dummy shaft (ST31181001)
V3Spacer [thickness: 2.50 mm (0.0984 in)]
V4Feeler gauge
2. To simplify the job, make a chart, like the one below, to orga-
nize your calculations.
LETTERSHUNDREDTHS OF

H: Head number
D¢: Figure marked on dummy shaft
S: Figure marked on height gauge
N: Measuring clearance
3. Write the following numbers down the chart.

4. Place pinion rear bearing inner cone and Tools on gear carrier.
Tool number:
ST31181001
5. Attach Tool (Height gauge) to gear carrier, and measure the
clearance between the height gauge tip and the dummy shaft
face.
Tool number:
ST31251000
6. Substitute these values into the equation to calculate the thick-
ness of the washer.
If values signifying H, D¢and S are not given, regard them as
zero and calculate.
T (Thickness of washer)
=Nþ[(HþD¢þ S) x 0.01] + 3.05

Disassembly
1. Remove side bearing inner cone with Tool. For removal
procedure, refer to ordinary differential case.
2. Loosen ring gear bolts in a criss-cross pattern.
3. Tap ring gear off the gear with a soft hammer.
4. Put marks on both differential cases.
5. Loosen screws on differential cases A and B using a press.
Tool number: ST33081000
6. Separate differential cases A and B.
7. Drive out pinion mate shaft lock pin with Tool.
Draw out component parts.
