2014 JEEP GRAND CHEROKEE transfer case fluid

Maintenance
After driving through deep water, inspect your vehicle
fluids and lubricants (engine oil, transmission oil, axle,
transfer case) to assure the fluids have not been contami-
nated. Contaminated fluid (milky, foamy in appearance)
should be flushed/changed as soon as possible to pre-
vent component damage.
Driving In Snow, Mud And Sand
In heavy snow, when pulling a load, or for additional
control at slower speeds, shift the transmission to a low
gear and shift the transfer case to 4WD LOW if necessary.
Refer to “Four-Wheel Drive Operation” in “Starting and
Operating” for further information. Do not shift to a
lower gear than necessary to maintain forward motion.
Over-revving the engine can spin the wheels and traction
will be lost.Avoid abrupt downshifts on icy or slippery roads, be-
cause engine braking may cause skidding and loss of
control.
Hill Climbing
NOTE:
Before attempting to climb a hill, determine the
conditions at the crest and/or on the other side.
Before climbing a steep hill, shift the transmission to a
lower gear and shift the transfer case to 4WD LOW. Use
first gear and 4WD LOW for very steep hills.
If you stall or begin to lose forward motion while
climbing a steep hill, allow your vehicle to come to a stop
and immediately apply the brakes. Restart the engine,
and shift into REVERSE. Back slowly down the hill,
allowing the compression braking of the engine to help
regulate your speed. If the brakes are required to control
vehicle speed, apply them lightly and avoid locking or
skidding the tires.

The front axle fill and drain plugs should be tightened to
22 to 29 ft lbs (30 to 40 N·m).
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Rear Axle Fluid Level Check
The rear axle oil level needs to be no lower than 1/8 in
(3 mm) below the bottom of the fill hole.
The rear axle fill and drain plugs should be tightened to
22 to 29 ft lbs (30 to 40 N·m) on axles with aluminum
housings. The rear axle fill and drain plugs should be
tightened to 22 to 52 ft lbs (30 to 70 N·m) on axles with
cast iron housings.
CAUTION!
Do not overtighten the plugs as it could damage them
and cause them to leak.
Selection Of Lubricant
Use only the manufacturer’s recommended fluid. Refer
to “Fluids, Lubricants, and Genuine Parts” in “Maintain-
ing Your Vehicle” for further information.
Transfer Case
Fluid Level Check
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons
the exterior surfaces of the transfer case assembly should
be inspected. If oil leakage is suspected inspect the fluid
level. Refer to “Fluids, Lubricants, and Genuine Parts” in
“Maintaining Your Vehicle” for further information.7
