Repacking Front Wheel Bearing and Axle Joint
Grease
FRONT WHEEL BEARING GREASE
Apply multi-purpose grease sparingly to the following parts:
+Threaded portion of spindle
+Contact surface between wheel bearing washer and outer
wheel bearing
+Grease seal lip
+Wheel hub (as shown at the left)
AXLE JOINT GREASE
+Drain approximately 2 liters (1-3/4 Imp qt) of differential oil.
+Remove knuckle spindle.
+Slightly pull out axle and repack axle joint with recommended
grease.
Refer to FA section.
Checking Free-running Hub Grease
Check free-running hub grease for leakage and water or dust entry.
Checking Water Entry in Knuckle Flange
+Check for water entry in knuckle ¯ange by removing one bolt
of lower knuckle ¯ange bearing cap and probing with a suitable
thin bar.
+After checking, be sure to reinstall the bolt to a tightening torque
of 30 to 40 Nzm (3.1 to 4.1 kg-m, 22 to 30 ft-lb).
Checking Brake Fluid Level and Leaks
If ¯uid level is extremely low, check brake system for leaks.

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)

Precautions
+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.
+After installing removed suspension parts, check wheel
alignment and adjust if necessary.
+Always torque brake lines when installing.

Rear Axle and Rear Suspension Parts
Check rear axle and rear suspension parts for excessive play, wear
or damage.
+Shake each rear wheel to check for excessive play.
+Retighten all nuts and bolts to the speci®ed torque.
Tightening torque:
Refer to REAR SUSPENSION, RA-12.
+Check shock absorber for oil leakage or other damage.
+Check shock absorber bushing for excessive wear or other
damage.
Rear Wheel Bearing
+Check that wheel bearings operate smoothly.
+Check axial end play.

6. Install a new wheel bearing lock washer.
7. Tighten wheel bearing lock nut to speci®ed torque.
: 441 - 490 Nzm (45 - 50 kg-m, 325 - 362 ft-lb)
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.
