1999 NISSAN PATHFINDER differential

could cause early tire wear, possibly
degraded 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. A spare tire of the same size,
brand, construction and tread pattern
must also be used. Failure to do so may
result in a circumference difference be-
tween tires on the front and rear axleswhich will cause excessive tire wear and
may damage the transmission, transfer
case and differential gears.
If excessive tire wear is found, it is recom-
mended that all four tires be replaced with tires
of the same size, brand, construction and
tread pattern. The tire pressure and wheel
alignment should also be checked and cor-
rected as necessary. Contact your NISSAN
dealer.Wheel balanceUnbalanced wheels may affect vehicle han-
dling and tire life. Even with regular use,
wheels can get out of balance. Therefore, they
should be balanced as required.
Wheel balance service should be performed
with the wheels off the vehicle. Spin balancing
the rear wheels on the vehicle could lead to
transmission damage.Care of wheelsIWash the wheels when washing the vehicle
to maintain their appearance.
IClean the inner side of the wheels when the
wheel is changed or the underside of the
vehicle is washed.IDo not use abrasive cleaners when wash-
ing the wheels.
IInspect wheel rims regularly for dents or
corrosion. This may cause loss of pressure
or damage the tire bead.
IWe recommend that the road wheels be
waxed to protect against road salt in areas
where it is used during winter.

Emission control system
maintenanceAdditional information on the following
items with * is found in the ª8. Do-it-
yourselfº section.
Drive belts*:
Check drive belts for wear, fraying or cracking
and also for proper tension. Replace the drive
belts if found damaged.
Air filter:
Under normal driving conditions, 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. Conse-
quently, the element may have to be replaced
more frequently.
EVAP vapor lines:
Check vapor lines and connections for failure
or looseness. If leaks are found, replace the
lines.
Fuel lines:
Check the fuel hoses, piping and connections
for leaks, looseness or deterioration. Replace
any parts if they are damaged.Fuel filter:
If the vehicle is operated under extremely
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 maintenance schedule. However, un-
der severe driving 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 & cables:
Check the brake lines and hoses (including
brake booster vacuum hoses, connections &
check valve) and parking brake cables for
proper attachment, leaks, cracks, chafing,
abrasion, deterioration, etc.
Brake pads, rotors, drums & linings:
Check these and the other neighboring brake
components for wear, deterioration and leaks.
Under severe driving conditions, they may
have to be inspected more frequently.
Manual and automatic transmission,
transfer & differential gear fluid:
Visually inspect for signs of leakage and re-
place oil for limited-slip differential. Under se-
vere driving conditions, the oil should be re-
placed at the specified interval.
Steering gear, linkage & transfer gear,
axle & suspension parts & drive axle
shaft boots:
Check for damage, looseness and leakage of
oil or grease. Under severe driving conditions,
more frequent inspection should be per-
formed.
