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.
