CAUTION!
• When installing the power distribution center cover, it
is important to ensure the cover is properly positioned
and fully latched. Failure to do so may allow water to
get into the power distribution center and possibly
result in an electrical system failure.
• When replacing a blown fuse, it is important to use
only a fuse having the correct amperage rating. The use
of a fuse with a rating other than indicated 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. WARNING!
• Do not attempt to change a tire on the side of the vehicle
close to moving traffic. Pull far enough off the road to
avoid the danger of being hit when operating the jack
or changing the wheel.
• Being under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never put any part of your body
under a vehicle that is on a jack. If you need to get
under a raised vehicle, take it to a service center where
it can be raised on a lift.
• Never start or run the engine while the vehicle is on a
jack.

IN CASE OF EMERGENCY 391
4500/5500 Models
These vehicles do not come equipped with a jack.

lifting this vehicle during a tire change.
• If working on or near a roadway, be extremely careful
of motor traffic.

IN CASE OF EMERGENCY 393
Jack Warning Label 1. If equipped, remove the spare wheel, jack, and tools from
storage.
2. Using the lug wrench, loosen, but do not remove, the lug
nuts by turning them counterclockwise one turn while
the wheel is still on the ground.• To assure that spare tires, flat or inflated, are securely
stowed, spares must be stowed with the valve stem
facing the ground. WARNING! (Continued) CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.

394 IN CASE OF EMERGENCY
3. When changing the front wheel, assemble the jack driver
to the jack and connect the jack driver to the extension
tube. Place the jack under the axle as close to the tire as
possible with the jack driver extending to the front.
Connect the extension tubes and lug wrench.
Front Jacking Locations
When changing a rear wheel, assemble the jack driver to
the jack and connect the jack driver to the extension tubes.
Securely place the jack under the sway bar bracket (unless
both tires are flat on one side, then place jack under shock
bracket) facing forward in vehicle. Connect the extension
tubes and lug wrench. Rear Jacking Location
Before raising the wheel off the ground, make sure that
the jack will not damage surrounding truck parts and
adjust the jack position as required.
NOTE:
If the jack will not lower by turning the dial (thumbwheel) by
hand, it may be necessary to use the jack driver in order to
lower the jack.
4. By rotating the lug wrench clockwise, raise the vehicle
until the wheel just clears the surface.

IN CASE OF EMERGENCY 395
5. Remove the lug nuts and pull the wheel off. Install the
spare wheel and lug nuts with the cone shaped end of the
nuts toward the wheel on single rear wheel (SRW)
models. On dual rear wheel models (DRW) the lug nuts
are a two-piece assembly with a flat face. Lightly tighten
the nuts. To avoid risk of forcing the vehicle off the jack,
do not fully tighten the nuts until the vehicle has been
lowered.
6. Using the lug wrench, finish tightening the nuts using a
crisscross pattern. For the proper lug nut torque specifica -
tions refer to “Wheel And Tire Torque Specifications” in
“Technical Specifications.” If in doubt about the correct
tightness, have them checked with a torque wrench by an
authorized dealer or at a service station. 7. Install wheel center cap (if equipped) and remove wheel
blocks. Do not install chrome or aluminum wheel center
caps on the spare wheel. This may result in cap damage.
8. Lower the jack to its fully closed position. If the jack will
not lower by turning the dial (thumbwheel) by hand, it
may be necessary to use the jack driver in order to lower
the jack. Stow the replaced tire, jack, and tools as previ -
ously described.
9. Adjust the tire pressure when possible.WARNING!
Raising the vehicle higher than necessary can make the
vehicle less stable. It could slip off the jack and hurt
someone near it. Raise the vehicle only enough to
remove the tire. WARNING!
A loose tire or jack thrown forward in a collision or hard
stop, could endanger the occupants of the vehicle.
Always stow the jack parts and the spare tire in the
places provided.

396 IN CASE OF EMERGENCY
Dual Rear Wheels
Slots in the wheels will assist in properly orienting the inner
and outer wheels. Align these slots when assembling the
wheels for best access to the tire valve on the inner wheel.
The tires of both dual wheels must be completely off the
ground when tightening to insure wheel centering and
maximum wheel clamping.
Dual wheel models require a special heavy-duty lug nut
tightening adapter (included with the vehicle) to correctly
tighten the lug nuts. Also, when it is necessary to remove and
install dual rear wheels, use a proper vehicle lifting device.
NOTE:
When installing a spare tire (if equipped) as part of a dual
rear wheel end combination, the tire diameter of the two
individual tires must be compared. If there is a significant
difference, the larger tire should be installed in a front loca -
tion. The correct direction of rotation for dual tire installa -
tions must also be observed
It is recommended that wheel stud nuts be kept torqued to
specifications at all times. Torque wheel stud nuts to specifi -
cations at each lubrication interval.
Refer to “Wheel And Tire Torque Specifications” in “Tech -
nical Specifications” for further information. Wheel Nuts
All wheel nuts should be tightened occasionally to eliminate
the possibility of wheel studs being sheared or the bolt holes
in the wheels becoming elongated. This is especially
important during the first few hundred miles/kilometers of
operation to allow the wheel nuts to become properly set. All
wheel nuts should first be firmly seated against the wheel.
The wheel nuts should then be tightened to recommended
torque. Tighten the wheel nuts to final torque in increments.
Progress around the bolt circle, tightening the wheel nut
opposite to the wheel nut just previously tightened until
final torque is achieved.
Refer to “Wheel And Tire Torque Specifications” in “Tech -
nical Specifications” for further information.
To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builder’s Guide for information on
stowing your spare tire (if equipped).

IN CASE OF EMERGENCY 397
Hub Caps/Wheel Covers — If Equipped
The hub caps must be removed before raising the vehicle off
the ground.
For 3500 single rear wheel (SRW) models, use the flat end of
the lug wrench to hook and pull off the hub cap. Find the
opening in the hub cap, insert the lug wrench, and pull off
the cap. If you need to pry against the wheel, protect the
wheel surface. Lug Wrench Insertion Location — Hub Cap
On 3500 models with dual rear wheels (DRW), you must first
remove the hub caps—use the procedure noted for the single
rear wheel. For the wheel covers (wheel skins), insert the flat
end of the lug wrench between the outer edge of the wheel
cover and the wheel. Pry against the wheel to remove the
wheel cover. Repeat this procedure around the wheel until
the cover pops off.CAUTION!
Use extreme caution when removing the front and rear
wheel covers. Damage can occur to the center cap and/or
the wheel if screwdriver type tools are used. A pulling
motion, not a pry off motion, is recommended to remove
the caps.

398 IN CASE OF EMERGENCY
Lug Wrench Insertion Location — Wheel Cover
Replace the wheel covers using a rubber mallet to ease the
installation. Align the wheel cover vent holes to the wheel
vent holes. Tap on the wheel cover as needed to firmly seat it
evenly around the wheel. JUMP STARTING
If your vehicle has a discharged battery, it can be jump
started using a set of jumper cables and a battery in another
vehicle, or by using a portable battery booster pack. Jump
starting can be dangerous if done improperly, so please
follow the procedures in this section carefully.
NOTE:
When using a portable battery booster pack, follow the
manufacturer's operating instructions and precautions.CAUTION!
• Use a pulling motion to remove the hub cap. Do not use
a twisting motion when removing the hub cap, damage
to the hub cap; finish may occur.
• The rear hub caps on the dual rear wheel has two pull
off notches. Make sure that the hook of the jack handle
driver is located squarely in the cap notch before
attempting to pull off. WARNING!
Do not attempt jump starting if the battery is frozen. It
could rupture or explode and cause personal injury.
CAUTION!
Do not use a portable battery booster pack or any other
booster source with a system voltage greater than 12 Volts or
damage to the battery, starter motor, alternator or electrical
system may occur.
