Driving Through Water
Extreme care should be taken crossing any type of water.
Water crossings should be avoided if possible and only be
attempted when necessary, in a safe responsible manner.
You should only drive through areas which are desig-
nated and approved. You should tread lightly and avoid
damage to the environment. You should know your
vehicles abilities and be able to recover it if something
goes wrong. You should never stop or shut a vehicle off
when crossing deep water unless you ingested water into
the engine air intake. If the engine stalls do not attempt to
restart it. Determine if it has ingested water first. The key
to any crossing is low and slow. You want to use 1st gear
in 4L (low) and proceed very slowly with a constant slow
speed (3-5 mph maximum) and light throttle. Keep the
vehicle moving; do not try to accelerate through the
crossing. After crossing any water higher than the bottom
of the axle differentials, you should inspect all of the
vehicle fluids for signs of water ingestion.CAUTION!
Water ingestion into the axles, transmission, transfer
case, engine or vehicle interior can occur if you drive
too fast or through too deep of water. Water can cause
permanent damage to engine, driveline or other
vehicle components and your brakes will be less
effective once wet and/or muddy
²Before You Cross Any Type Of Water± As you
approach any type of water you need to determine if
you can cross it safely and responsibly. If necessary, get
out and walk through the water or probe it with a
stick. You need to be sure of its depth, approach angle,
current and bottom condition. Be careful of murky or
muddy waters, check for hidden obstacles. Make sure
you will not be intruding on any wildlife and you can
recover the vehicle if necessary. The key to a safe

HOISTING
A conventional floor jack may be used at the jacking
locations, refer to the graphics that show jacking loca-
tions. However, a floor jack or frame hoist must never be
used on any other parts or the underbody.
CAUTION!
Never use a floor jack directly under the differential
housing of a loaded truck or damage to your vehicle
may result.
JUMP-STARTING
You should not try to start your vehicle by pushing or
towing. Vehicles equipped with an automatic transmis-
sion cannot be started this way and pushing or towing a
vehicle equipped with a manual transmission may over-
heat and damage the catalytic converter. Also, there is a
greater risk of an accident when a vehicle is being pushed
or towed. If the vehicle has a discharged battery, booster
cables may be used to obtain a start from a booster
battery or the battery in another vehicle. This type of start
can be dangerous if done improperly, so follow this
procedure carefully.
WHAT TO DO IN EMERGENCIES 375

Rear Axle And 4x4 Front Driving Axle Fluid Level
Refer to Fluids, Lubricants and Genuine Parts for the
correct Fluid type. 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.
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 for the Manufacturer's C205F HD Front
Axles. The fluid level should be 5/8º (16 mm) below on
9 1/4º Manufacturer's Rear Axles.
For all 2500 Model axles, the fluid level should be 1/4º  
1/4º (6.4 mm   6.4 mm) below the fill hole on the 9.25º
Front and 3/4º  1/4º (19 mm   6.4 mm) on 10.5º Rear
axles.
Drain and Refill
Vehicles operated in normal service do not have regularly
scheduled oil changes. If fluid has become contaminated
with water or to provide the correct viscosity grade, drain
and refill.
Lubricant Selection
Refer to Fluids, Lubricants and Genuine Parts for correct
fluid type.
NOTE:The presence of water in the gear lubricant will
result in corrosion and possible failure of differential
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
Power Wagon AxlesDO NOT REQUIREany limited slip
oil additive (friction modifiers).
