SERVICING AND MAINTENANCE 309
(Continued)
REAR AXLE AND 4X4 FRONT DRIVING
A
XLE FLUID LEVEL
For normal service, periodic fluid level checks
are not required. When the vehicle is serviced
for other reasons the exterior surfaces of the
axle assembly should be inspected. If gear oil
leakage is suspected inspect the fluid level. This
inspection should be made with the vehicle in a
level position.
The fluid level should be even with the bottom
of the fill hole (within 1/4 inch (6.4 mm) of edge
of hole) for the front axle and rear axle.
Drain And Refill
For the proper maintenance intervals
Ú page 287.
Lubricant Selection
For further information Ú page 355.
NOTE:
The presence of water in the gear lubricant will
result in corrosion and possible failure of differ-
ential components. Operation of the vehicle in
water, as may be encountered in some
off-highway types of service, will require
draining and refilling the axle to avoid damage.
Limited-Slip Differentials
Rear axles equipped with a Limited Slip
Differential require that 5 oz. (148 ml) Mopar
Limited Slip Additive be added to the gear
lubricant Ú page 355. The Mopar Limited Slip
Additive should be added to the gear lubricant
whenever a fluid change is made to an axle
equipped with a Limited Slip Differential.
NOTE:
When refilling an axle with a Limited Slip Differ-
ential, (which requires a Limited Slip Additive),
the Limited Slip Additive should be added
before the gear lubricant is added to insure
proper additive fill.
TRANSFER CASE
Fluid Level Check
This fluid level can be checked by removing the
filler plug. The fluid level should be to the
bottom edge of the filler plug hole (or at least
within 1/8 inch of the bottom) with the vehicle
in a level position.
Drain And Refill
For the proper maintenance intervals
Ú page 287.
Selection Of Lubricant
Use only the recommended fluid Ú page 355.
FUSES
General Information
WARNING!
When replacing a blown fuse, always use
an appropriate replacement fuse with the
same amp rating as the original fuse. Never
replace a fuse with another fuse of higher
amp rating. Never replace a blown fuse with
metal wires or any other material. Do not
place a fuse inside a circuit breaker cavity
or vice versa. Failure to use proper fuses
may result in serious personal injury, fire
and/or property damage.
Before replacing a fuse, make sure that the
ignition is off and that all the other services
are switched off and/or disengaged.
If the replaced fuse blows again, contact an
authorized dealer.
