SERVICING AND MAINTENANCE 427
Drain And Refill
For the proper maintenance intervals
Ú page 395.
Lubricant Selection
For further information Ú page 478.
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 478. 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.

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.
If a general protection fuse for safety
systems (air bag system, braking system),
power unit systems (engine system, trans-
mission system) or steering system blows,
contact an authorized dealer.
