1998 NISSAN PICK-UP tow

4-WHEEL DRIVE MODELS
NISSAN recommends that a dolly be used as illustrated when
towing 4-wheel drive models.
Towing with four wheels on the ground or towing with front or rear wheels on the ground
Observe the following restricted towing speeds and distances.
Speed: Below 95 km/h (60 MPH)
Distance: Less than 800 km (500 miles)
If the speed or distance must necessarily be greater, remove the front and rear propeller shafts beforehand
to prevent damage to the transmission.

GI-52

Towing Point
Never tow the vehicle using only the towing points. To avoid damaging the vehicle body, use proper
towing equipment when towing.
VEHICLE RECOVERY (Freeing a stuck vehicle)
lPulling devices should be routed so they do not touch any
part of the suspension, steering, brake or cooling systems.
lAlways pull the cable straight out from the front or rear of the
vehicle. Never pull the vehicle at a sideways angle.
lPulling devices such as ropes or canvas straps are not rec-
ommended for use for vehicle towing or recovery.

tions or in areas where ambient tempera-
tures are either extremely low or extremely
high
F Ð Driving in high humidity areas or in mountain-
ous areasG Ð Driving in areas using salt or other corrosive
materials
H Ð Driving on rough and/or muddy roads or in
the desert

CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system with cap tester to check for
leakage.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher pressure than the specified value may cause damage
to the radiator.
Checking Fuel Lines
Inspect fuel lines and tank for improper attachment and for leaks,
cracks, damage, loose connections, chafing and deterioration.
If necessary, repair or replace malfunctioning parts.
CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end
is 3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
Changing Fuel Filter
WARNING:
Before removing fuel filter, release fuel pressure from fuel
line.
1. Remove fuse for fuel pump.
2. Start engine.
3. After engine stalls, crank engine two or three times to make
sure that fuel pressure is released.
4. Turn ignition switch OFF and install fuse for fuel pump.
5. Loosen fuel hose clamps.
6. Replace fuel filter.
lBe careful not to spill fuel or engine compartment. Place
a shop towel to absorb fuel.
lUse a high-pressure type fuel filter. Do not use a syn-
thetic resinous fuel filter.
lWhen tightening fuel hose clamps, refer to ``Checking
Fuel Lines'', MA-18.

Checking Body Corrosion
Visually check the body sheet metal panel for corrosion, paint damage (scratches, chipping, rubbing, etc.)
or damage to the anti-corrosion materials. In particular, check the following locations.
Hemmed portion
Hood front end, door lower end, trunk lid rear end, etc.
Panel joint
Side sill of rear fender and center pillar, rear wheel housing of rear fender, around strut tower in engine
compartment, etc.
Panel edge
Trunk lid opening, sunroof opening, fender wheelarch flange, fuel filler lid flange, around holes in panel, etc.
Parts contact
Waist molding, windshield molding, bumper, etc.
Protectors
Damage or condition of mudguard, fender protector, chipping protector, etc.
Anti-corrosion materials
Damage or separation of anti-corrosion materials under the body.
Drain holes
Condition of drain holes at door and side sill.
When repairing corroded areas, refer to the Corrosion Repair Manual.

JOURNAL
1. Place matching marks on propeller shaft and flange or yoke.
2. Remove snap ring.
3. Remove pushed out journal bearing by lightly tapping yoke
with a hammer, taking care not to damage journal and yoke
hole.
4. Remove bearing at opposite side in above operation.
Put marks on disassembled parts so that they can be rein-
stalled in their original positions.
Assembly
CENTER BEARING
lWhen installing center bearing, position the ``F'' mark on cen-
ter bearing toward front of vehicle.
lApply a coat of multi-purpose lithium grease containing
molybdenum disulfide to the end face of the center bear-
ing and both sides of the washer.

Precautions for SRS ``AIR BAG'' Service
lDo not use a circuit tester to check SRS circuits unless instructed to in this Service Manual.
lBefore servicing the SRS, turn ignition switch ``OFF'', disconnect both battery cables and wait for at least
3 minutes.
For approximately 3 minutes after the cables are removed, it is still possible for the air bag to deploy.
Therefore, do not work on any SRS connectors or wires until at least 3 minutes have passed.
lFor 2WD models, do not separate diagnosis sensor unit from steering wheel.
lFor 4WD models, diagnosis sensor unit must always be installed with their arrow marks ``S'' pointing
towards the front of the vehicle for proper operation. Also check diagnosis sensor unit for cracks,
deformities or rust before installation and replace as required.
lThe spiral cable must be aligned with the neutral position since its rotations are limited. Do not attempt
to turn steering wheel or column after removal of steering gear.
lHandle air bag module carefully. Always place it with the pad side facing upward.
lConduct self-diagnosis to check entire SRS for proper function after replacing any components.
