JACKING AND TIRE CHANGING
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.
• 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.
(Continued)
WARNING! (Continued)
•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. The vehicle should be
jacked on a firm level surface only. Avoid ice or
slippery areas.
4500/5500 Models
These vehicles do not come equipped with a jack.
NOTE: Jacking and tire changing on 4500/5500 models
should be performed by an authorized dealer, or knowl-
edgeable service personnel with the appropriate heavy
duty equipment, like a tire service company.

Preparations For Jacking
1. Park the vehicle on a firm, level surface. Avoid ice orslippery areas.
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.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK (automatic transmis- sion) or REVERSE (manual transmission). On 4-Wheel
drive vehicles, shift the transfer case to the “4L”
position.
5. Turn OFF the ignition. 6. Block both the front and rear of the wheel diagonally
opposite of the jacking position. For ex-
ample, if changing the right front tire,
block the left rear wheel.
NOTE: Passengers should not remain in the
vehicle when the vehicle is being jacked.Jacking Instructions

WARNING!(Continued)
•Block the wheel diagonally opposite the wheel to
be raised.
• Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
• Never start or run the engine with the vehicle on a
jack.
• Do not let anyone sit in the vehicle when it is on a
jack.
• Do not get under the vehicle when it is on a jack. If
you need to get under a raised vehicle, take it to a

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

WARNING! (Continued)
•To assure that spare tires, flat or inflated, are
securely stowed, spares must be stowed with the
valve stem facing the ground.

locations other than those indicated in the Jacking
Instructions for this vehicle.

1. If equipped, remove the spare wheel, jack, and toolsfrom 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. 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.
When changing a rear wheel, assemble the jack drive
tube to the jack and connect the drive tube to the
extension tube. 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 jack tube extension and lug wrench.

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 drive tube in order to lower the jack. 4. By rotating the wheel wrench clockwise, raise the
vehicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle unstable and cause a collision. 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 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.

bolt circle, tightening the wheel nut opposite to the wheel
nut just previously tightened until final torque is
achieved.
To Stow The Flat Or Spare — If Equipped
Refer to Upfitters Body Builders Guide for information
on stowing your spare tire (if equipped).
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 of 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 PROCEDURES
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!
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.
