Preparation for Disassembly
CHECKING DIFFERENTIAL TORQUE
Measure differential torque with Tool.
If it is not within the speci®cations, inspect components of limited
slip differential.
Differential torque:
108 - 137 Nzm (11 - 14 kg-m, 80 - 101 ft-lb)

10. Install differential case A on differential case B. Align the match-
ing marks on the cases, then install screws while pushing dif-
ferential case down using a press.
Press force:
7,846 N (800 kg, 1,764 lb)
11. After all parts have been assembled, check and adjust the fol-
lowing:
DIFFERENTIAL TORQUE INSPECTION
a. Place side gear in a vise with Tool into the gear splines.
b. Turn side gear several times, then measure the differential
torque after side gear begins to rotate in order to determine
whether it is within the speci®ed range. If it is not, adjust it by
selecting a friction disc. (Refer to SDS for adjustment parts.)
Differential torque:
108 - 137 Nzm (11 - 14 kg-m, 80 - 101 ft-lb)
Tool number: KV38106400
SIDE GEAR BACKLASH INSPECTION
Check backlash of side gear on both sides. Using a feeler gauge,
measure clearance between side gear and thrust washer. If it is not
within speci®cations, adjust it by selecting a thrust washer. (Refer
to SDS.)
Side gear backlash:
Differential case A side
0.05 - 0.20 mm (0.0020 - 0.0079 in)
Differential case B side
0.05 - 0.20 mm (0.0020 - 0.0079 in)
12. After checking and adjusting, tighten ring gear bolts in a criss-
cross fashion.
13. Bend up lock straps to lock bolts in place.
14. Install side bearing inner race with Tool.

6. Install drive pinion bearing spacer, pinion bearing adjusting
shim and drive pinion in gear carrier.
7. Insert companion ¯ange into drive pinion by tapping the com-
panion ¯ange with a soft hammer.
8. Tighten pinion nut to the speci®ed 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 measure
pinion bearing preload.
Tool number: ST3127S000
Pinion bearing preload (with front oil seal):
1.4 - 1.7 Nzm (14 - 17 kg-cm, 12 - 15 in-lb)
If preload is out of speci®cation, adjust the thickness of spacer and
shim combination by replacing shim and spacer with thinner one.
+Start from the combination of thickest spacer and shim.
+Combine each spacer and shim thickness one by one until the
correct speci®cation are achieved.

+When installing rubber parts, ®nal tightening must be car-
ried out under unladen condition* with tires on ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack,
hand tools and mats in designated positions.
+Use ¯are nut wrench when removing and installing brake
tubes.

Be sure to bend bearing lock washer up.
8. Check wheel bearing preload.
a. Turn bearing cage (with respect to axle shaft) two or three
times. It must turn smoothly.
b. Attach spring gauge to bearing cage bolt (as shown at left) and
pull it at a speed of 10 rpm to measure preload.
Spring gauge indication:
8.8 - 42.2 N (0.9 - 4.3 kg, 2.0 - 9.5 lb)
9. Install new oil seal to rear axle housing using a suitable tool.
After installing new oil seal, coat sealing lip with multi-purpose
grease.
10. Install new O-ring to rear axle housing.
11. Press ABS sensor rotor onto axle shaft until it contacts wheel
bearing lock nut.
12. Install axle shafts in rear axle housing.
Be careful not to damage oil seal.

Supplemental Restraint System (SRS) ``AIR
BAG'' and ``SEAT BELT PRE-TENSIONER''
The Supplemental Restraint System such as ``AIR BAG'' and ``SEAT BELT PRE-TENSIONER'' used along with
a seat belt, helps to reduce the risk or severity of injury to the driver and front passenger in a frontal collision.
The SRS system composition which is available to NISSAN MODEL Y61 is as follows (The composition var-
ies according to the destination.):
Driver air bag module (located in the center of the steering wheel), front passenger air bag module (located
on the instrument panel on passenger side), seat belt pre-tensioner, a diagnosis sensor unit, warning lamp,
wiring harness and spiral cable.
Information necessary to service the system safely is included in theRS sectionof this Service Manual.
WARNING:
+To avoid rendering the SRS inoperative, which could increase the risk of personal injury or death
in the event of a collision which would result in air bag in¯ation, all maintenance must be performed
by an authorized NISSAN dealer.
+Improper maintenance, including incorrect removal and installation of the SRS, can lead to per-
sonal injury caused by unintentional activation of the system. For removal of Spiral Cable and Air
Bag Module, see the RS section.
+Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. Spiral cable and wiring harnesses covered with yellow insulation either just before
the harness connectors or for the complete harness are related to the SRS.
Precautions for Steering System
+Before disassembly, thoroughly clean the outside of the unit.
+Disassembly should be done in a clean work area. It is important to prevent the internal parts from
becoming contaminated by dirt or other foreign matter.
+Place disassembled parts in order, on a parts rack, for easier and proper assembly.
+Use nylon cloths or paper towels to clean the parts; common shop rags can leave lint that might
interfere with their operation.
+Before inspection or reassembly, carefully clean all parts with a general purpose, non-¯ammable
solvent.
+Before assembly, apply a coat of recommended ATF* to hydraulic parts. Vaseline may be applied
to O-rings and seals. Do not use any grease.
+Replace all gaskets, seals and O-rings. Avoid damaging O-rings, seals and gaskets during instal-
lation. Perform functional tests whenever designated.
