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

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.

Removal and Installation
Before removal, clean gear housing and oil pump exteriors
using a steam cleaner. Then dry with compressed air.
+Plug openings of gear housing, and securely locate hose con-
nectors at a position higher than oil pump and cover with paper
towels.
+Be extremely careful to prevent entry of foreign matter into
hoses through connectors.
+When installing pitman arm, align four grooves of pitman arm
serrations with four projections of sector shaft serrations, and
install and tighten lock washer and nut.
Inspection
Do not disassemble for power steering gear assembly.
TURNING TORQUE MEASUREMENT
1. Measure turning torque at 360É position.
a. Install steering gear on Tool.
SST774C
SST040-A
POWER STEERING GEAR (Model: PB69K)
ST-13

b. Turn stub shaft all the way to right and left several times.
c. Measure turning torque at 360É position from straight-ahead
position with Tools.
Turning torque at 360É
0.15 - 0.78 Nzm (1.5 - 8.0 kg-cm, 1.3 - 6.9 in-lb)
2. Measure turning torque at straight-ahead position.
Straight-ahead position is a position where stub shaft is
turned 2.14 turns (two full turns and 50É) from lock position.
Turning torque at straight-ahead position:
0.2 - 0.5 Nzm (2 - 5 kg-cm, 1.7 - 4.3 in-lb)
higher than turning torque at 360É
Maximum turning torque:
0.44 - 1.18 Nzm (4.5 - 12 kg-cm, 3.9 - 10.4 in-lb)
3. Check sector shaft end play in neutral position.
End play:
Less than 0.1 mm (0.004 in)
If turning torque and end play are not within speci®cations,
replace power steering gear assembly.
