388 SERVICING AND MAINTENANCE
Lubricant Selection
Refer to “Fluids And Lubricants” in “Technical
Specification” for further information.
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. Refer to “Fluids And Lubricants” in
“Technical Specification” for further
information. 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.
Drain And Refill
Refer to the “Maintenance Plan” for the proper
maintenance intervals.
Transfer Case
Selection Of Lubricant

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
Refer to the “Maintenance Plan” in this section
for the proper maintenance intervals.
HOISTING
A conventional floor jack may be used at the
jacking locations. Refer to the graphics that
show jacking locations. However, a floor jack or
frame hoist must never be used on any other
parts of the underbody.
