SERVICING AND MAINTENANCE427
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 Úpage 476. 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 in (6.4 mm) of edge of hole)
for the front axle and rear axle.
Drain And Refill
For the proper maintenance intervals Úpage 394.
Lubricant Selection
For further information Ú page 476.
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 476. 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 a limited slip differential axle which
requires a friction modification additive, the
additive should be added before the gear lubricant
to ensure 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 within 1/8 inch of the
bottom) with the vehicle in a level position.
Drain And Refill
For the proper maintenance intervals Úpage 394.
Selection Of Lubricant
Use only the manufacturer recommended fluid
Úpage 476.
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.
The use of a fuse with a rating other than indi -
cated may result in a dangerous electrical
system overload. If a properly rated fuse
continues to blow, it indicates a problem in the
circuit that must be corrected. Never replace a
blown fuse with metal wires or any other mate -
rial. 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.
If a general protection fuse for safety systems
(air bag system, braking system), power unit
systems (engine system, transmission
system) or steering system blows, contact an
authorized dealer.

428SERVICING AND MAINTENANCE
The fuses protect electrical systems against
excessive current.
When a device does not work, you must check the
fuse element inside the blade fuse for a break/
melt.
Also, please be aware that using power outlets for
extended periods of time with the engine off may
result in vehicle battery discharge.
Blade Fuses

External Power Distribution Center
The Power Distribution Center is located in the
engine compartment near the battery. This center
contains cartridge fuses, micro fuses, relays, and
circuit breakers. A description of each fuse and
component may be stamped on the inside cover,
otherwise the cavity number of each fuse is
stamped on the inside cover that corresponds to
the following chart.CAUTION!
If it is necessary to wash the engine
compartment, take care not to directly hit the
fuse box, and the windshield wiper motors with
water.

3 — Blade fuse with a bad/not functional fuse el
-
ement (blown fuse)
CAUTION!
When installing the power distribution center
cover, it is important to ensure the cover is
properly positioned and fully latched. Failure
to do so may allow water to get into the power
distribution center and possibly result in an
electrical system failure.
