Checking Steering Wheel Turning Force (For
power steering)
1. Park vehicle on a level, dry surface and set parking brake.
2. Start engine and run at idle speed or 1,000 rpm.
3. Bring power steering fluid up to adequate operating tempera-
ture. [Make sure temperature of fluid is approximately 60 to
80ÉC (140 to 176ÉF).]
Tires need to be inflated to normal pressure.
4. Check steering wheel turning force when steering wheel has
been turned 360É from neutral position.
Steering wheel turning force:
PB48S-type
24.5 - 29.4 N (2.5 - 3.0 kg, 5.5 - 6.6 lb)
PB59K-type
39 N (4 kg, 9 lb) or less
5. If steering wheel turning force is out of specification, check
the following:
a. Hydraulic system. Refer to ``Checking Hydraulic System'',
ST-7.
b. Steering Column. Refer to ST-10.
c. Front suspension and axle. Refer to FA section (``Front Axle
and Front Suspension Parts'', ``ON-VEHICLE SERVICE'').
d. Steering gear turning torque. Refer to ``TURNING TORQUE
MEASUREMENT'', ST-19 (PB48S), or ST-27 (PB59K).
Checking Steering Wheel Play
lPlace wheels in a straight ahead position and check steer-
ing wheel play.
Steering wheel play:
35 mm (1.38 in) or less
lIf it is not within specification, check the following for loose
or worn components.
a. Steering column. Refer to ST-10.
b. Front suspension and axle. Refer to FA section (``Front Axle
and Front Suspension Parts'', ``ON-VEHICLE SERVICE'').
c. Steering gear. [Refer to ST-13 (manual steering),ST-19
(power steering PB48S), or ST-27 (power steering PB59K).]

Removal
1. Drain oil from transfer and transmission.
2. Remove front and rear propeller shaft. Refer to PD section
(``Removal and Installation'', ``PROPELLER SHAFT'').
Insert plug into rear oil seal after removing propeller shaft.
lBe careful not to damage spline, sleeve yoke and rear oil
seal, when removing propeller shaft.
3. Remove torsion bar spring. Refer to FA section (``Torsion Bar
Spring'', ``FRONT SUSPENSION''). Then remove second
crossmember.
4. Disconnect 4WD and neutral position switches.
5. Remove transfer control lever from transfer outer shift lever.
6. Separate transfer from transmission.
WARNING:
Support transfer while removing it.
Installation
lApply recommended sealant to mating surface to transmis-
sion.
Recommended sealant:
Nissan genuine part KP610-00250, Three Bond
1215 or equivalent
