WARNING!
The jack is designed to use as a tool for changing
tires only. The jack should not be used to lift the
vehicle for service purposes, unless suitable sup-
ports are placed under the vehicle as a safety mea-
sure. The vehicle should be jacked on a firm level
surface only. Avoid ice or slippery areas.
WARNING!
After using the jack and tools, always reinstall them
in the original carrier and location. While driving
you may experience, abrupt stopping, rapid accelera-
tion, or sharp turns. A loose jack, tools, bracket or
other objects in the vehicle may move around with
force, resulting in serious injury.
CHANGING A FLAT TIRE
Removing The Spare Tire
Remove the spare tire before attempting to jack the truck.
Attach the wheel wrench to the jack extension tube. Insert
the tube through the access hole between the lower
tailgate and the top of the bumper and into the winch
mechanism tube. Rotate the wheel wrench handle coun-
terclockwise until the spare tire is on the ground with
enough cable slack to allow you to pull it out from under
the vehicle. When the spare is clear, tilt the retainer at the
end of the cable and pull it through the center of the
wheel.

It is recommended that you stow the flat or spare to
avoid tangling the loose cable.
NOTE:The winch mechanism is designed for use with
the jack extension tube only. Use of an air wrench or other
power tools is not recommended and can damage the
winch.
Tire Changing Procedure
WARNING!
Getting under a jacked-up vehicle is dangerous. The
vehicle could slip off the jack and fall on you. You
could be crushed. Never get any part of your body
under a vehicle that is on a jack. Never start or run
the engine while the vehicle 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.
Do not raise this vehicle using a bumper jack. The jack is
designed as a tool for changing tires on this vehicle only.
It is not recommended that the jack be used for service
purposes or to lift more than one wheel at a time.
300 WHAT TO DO IN EMERGENCIES
Instructions
WARNING!
Carefully follow these tire changing warnings to
help prevent personal injury or damage to your
vehicle:
²Always park on a firm, level surface as far from
the edge of the roadway as possible before raising
the vehicle.
²Block the wheel diagonally opposite the wheel to
be raised.
²Apply the parking brake firmly before jacking.
²Never start the engine with the vehicle on a jack.
²Do not let anyone sit in the vehicle when it is on
a jack.
²Do not get under the vehicle when it is on a jack.
²Only use the jack in the positions indicated.
²If working on or near a roadway, be extremely
careful of motor traffic.
1. Remove the spare wheel, jack, and tools from storage.
2. Using the wheel wrench, loosen, but do not remove,
the wheel nuts by turning them counterclockwise one
turn while the wheel is still on the ground.
3. For 2500/3500 4x2 series trucks, when changing a
front wheel, place the bottle jack under the frame rail
behind the wheel. Locate the jack as far forward as
possible on the straight part of the frame.
For 2500/3500 4x4 series trucks, when changing the front
wheel, assemble the jack drive tube to the jack and
connect the drive tube to the extension tube. Place the
jack under the axle as close to the tire as possible with the
drive tubes extending to the front. Connect the jack tube
extension and wheel wrench.
302 WHAT TO DO IN EMERGENCIES
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause an accident. It could
slip off the jack and hurt someone near it. Raise the
vehicle only enough to remove the tire.
5. Remove the wheel nuts and pull the wheel off. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel on 2500/3500 single rear
wheel (SRW) models. On 3500 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 wheel wrench, finish tightening the nuts
using a crisscross pattern. Correct nut tightness is 135 ft.
lbs. (183 N´m) torque for 2500/3500 single rear wheel(SRW) models and 145 ft. lbs. (197 N´m) for 3500 dual rear
wheel models. If in doubt about the correct tightness,
have them checked with a torque wrench by your dealer
or at a service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle.
Always stow the jack parts and the extra tire and
wheel in the places provided.
7. Install wheel center cap 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 (thumb wheel) by

Slots in the wheels will assist in properly orienting the
inner and outer wheels. Align these slots when assem-
bling 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 cor-
rectly 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 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
location. Correct direction of rotation for dual tire instal-
lations must also be observed.
These dual rear wheels should be tightened as follows:

wheel. The nuts should then be tightened to recom-
mended torque. Tighten the nuts to final torque in
increments. Progress around the bolt circle, tightening
the nut opposite to the nut just previously tightened until
final torque is achieved. Recommended torques are
shown in the following chart.

To Stow The Flat Or Spare
Turn the wheel so that the valve stem is down. Slide the
wheel retainer through the center of the wheel and
position it properly across the wheel opening.
For convenience in checking the spare tire inflation, stow
with the valve stem toward the rear of the vehicle.Attach the wheel wrench to the extension tube. Rotate the
winch mechanism until the wheel is drawn into place
against the underside of the vehicle. Continue to rotate
until you feel the winch mechanism slip or click 3 or 4
times. It cannot be overtightened. Push against the tire
several times to be sure it is firmly in place.
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.
