differential NISSAN PATHFINDER 1998 R50 / 2.G Owners Manual

Tire wear and damageITires should be periodically in-
spected for wear, cracking, bulging
or objects caught in the tread. If ex-
cessive wear, cracks, bulging or deep
cuts are found, the tire should be
replaced.
IThe original tires have a built-in tread
wear indicator. When the wear indica-
tor is visible, the tire should bereplaced.
Replacing tires and wheelsWhen replacing a tire, use the same size,
speed rating and load carrying capacity as
originally equipped. See ªSpecificationsº in the
ª10. Technical and consumer informationº sec-
tion for tires and wheels.IThe use of tires other than those
recommended or the mixed use of
tires of different brands, construction
(bias, bias-belted or radial), or tread
patterns can adversely affect the ride,
braking, handling, ground clearance,
body-to-tire clearance, snow chain
clearance, speedometer calibration,
headlight aim and bumper height.
Some of these effects may lead to
accidents and could result in serious
personal injury.
IIf the wheels are changed for any
reason, always replace with wheels
which have the same offset dimen-
sion. Wheels of a different offset
could cause early tire wear, possiblydegraded vehicle handling character-
istics and/or interference with the
brake discs/drums. Such interference
can lead to decreased braking effi-
ciency and/or early brake pad/shoe
wear.
IDo not install a deformed wheel or
tire even if it has been repaired. Such
wheels or tires could have structural
damage and could fail without warn-
ing.
IThe use of retread tire is not rec-
ommended.
Four wheel drive modelsAlways use tires of the same size, brand,
construction (bias, bias-belted or ra-
dial), and tread pattern on all four
wheels. Failure to do so may result in a
circumference difference between tires
on the front and rear axles which will
cause excessive tire wear and may dam-
age the transmission, transfer case and
differential gears.

To ensure smooth, trouble-free, safe and eco-
nomical driving, NISSAN provides two differ-
ent maintenance schedules that may be used,
depending upon the conditions in which you
usually drive. These schedules contain both
distance and time intervals, up to 60,000 miles
(96,000 km)/48 months. For most people, the
odometer reading will indicate when service is
needed. However, if you drive very little, your
vehicle should be serviced at the regular time
intervals shown in the schedule.
After 60,000 miles (96,000 km) or 48
months, continue periodic maintenance at
the same mileage/time intervals.SCHEDULE 1Follow Periodic Maintenance Schedule 1 if
your driving habits frequently include one or
more of the following driving conditions:
IRepeated short trips of less than 5 miles
(8 km).
IRepeated short trips of less than 10
miles (16 km) with outside temperatures
remaining below freezing.
IOperating in hot weather in stop-and-go
rush hour traffic.
IExtensive idling and/or low speed driv-ing for long distances, such as police,
taxi or door-to-door delivery use.
IDriving in dusty conditions.
IDriving on rough, muddy, or salt spread
roads.
ITowing a trailer, using a camper or a
car-top carrier.
SCHEDULE 2Follow Periodic Maintenance Schedule 2 if
none of the driving conditions shown in Sched-
ule 1 apply to your driving habits.
Maintenance for offroad drivingWhenever you drive offroad through sand,
mud or water as deep as the wheel hub, more
frequent maintenance may be required of the
following items:G
Brake pads and discs
G
Brake lining and drums
G
Brake lines and hoses
G
Wheel bearing grease
G
Differential, transmission and transfer oil
G
Steering linkage
G
Propeller shafts and front drive shafts
G
Air cleaner filter
G
Clutch housing (See ªClutch housing drainº
in the ª8. Do-it-yourselfº section for check-
ing water entry.)
These items should be checked frequently to
assure safe and proper operation of your ve-
hicle.

EXPLANATION OF MAINTENANCE
ITEMSAdditional information on the following
items with * is found in the ª8. Do-it-
yourselfº section.Emission control system
maintenanceDrive belts*Check drive belts for wear, fray-
ing or cracking and also for proper tension.
Replace the drive belts if found damaged.
Air cleaner filterUnder normal driving condi-
tions, the air cleaner filter should be replaced
in accordance with the maintenance schedule.
However, driving the vehicle in dusty areas
may cause more rapid clogging of the element.
Consequently, the element may have to be
replaced more frequently.
Vapor linesCheck vapor lines and connec-
tions for failure or looseness. If leaks are
found, replace the lines.
Fuel linesCheck the fuel hoses, piping and
connections for leaks, looseness or deteriora-
tion. Replace any parts if they are damaged.
Fuel filterIf the vehicle is operated underextremely adverse weather conditions or in
areas where ambient temperatures are either
extremely low or extremely high, the filter
might become clogged. In such an event,
replace the filter immediately.
Engine coolant*Flush and refill the cooling
system.
Engine oil & oil filter*Under normal driving
conditions, the engine oil and oil filter should
be replaced in accordance with the mainte-
nance schedule. However, under severe driv-
ing conditions, they may have to be replaced
more frequently.
Spark plugs*Replace with new plugs having
the correct heat range.
Timing belt
Replace the timing belt for driving the cam-
shafts.
Chassis and body maintenanceBrake lines & cablesCheck the brake lines
and hoses (including brake booster vacuum
hoses, connections & check valve) and park-
ing brake cables for proper attachment, leaks,
cracks, chafing, abrasion, deterioration, etc.Brake pads, discs, drums & liningsCheck
these and the other neighboring brake compo-
nents for wear, deterioration and leaks. Under
severe driving conditions, they may have to be
inspected more frequently.
Manual and automatic transmission, trans-
fer & differential gear oilVisually inspect for
signs of leakage and replace oil for limited-slip
differential. Under severe driving conditions,
the oil should be replaced at the specified
interval.
Steering gear & linkage, axle & suspension
parts & drive axle shaft bootsCheck for
damage, looseness and leakage of oil or
grease. Under severe driving conditions, more
frequent inspection should be performed.
Steering linkage ball joints & front suspen-
sion ball jointsCheck the ball joints for dam-
age, looseness and grease leakage. Under
severe driving conditions, more frequent in-
spection should be performed.
Propeller shaft(s)Check the propeller
shaft(s) for damage, looseness and grease
leakage under severe driving condition
(
only).
