REMOVING THE SPARE TIRE

1. Remove the spare tire before attempting to
jack up the truck. Attach the lug wrench to
the extension tubes with the curved angle
facing away from the vehicle. Insert the
extension tube through the access hole
between the lower tailgate and the top of the
bumper and into the winch mechanism tube.

2. Rotate the lug wrench handle counter -
clockwise until the spare tire is on the
ground with enough cable slack to allow you
to pull it out from under the vehicle.

3. Pull the spare tire out from under the vehicle to gain access to the spare tire retainer.
4. Lift the spare tire with one hand to give
clearance to tilt the retainer at the end of
the cable.

Gaining Access To The Retainer

5. Pull the retainer through the center of the wheel.

WARNING!
After using the jack and tools, always reinstall
them in the original carrier and location.
While driving you may experience abrupt
stopping, rapid acceleration or sharp turns. A
loose jack, tools, bracket or other objects in
the vehicle may move around with force,
resulting in serious injury.

NOTE:
The winch mechanism is designed for use with
the extension tubes only. Use of an air wrench
or other power tools is not recommended and
can damage the winch.
PREPARATIONS FOR JACKING

1. Park the vehicle on a firm, level surface. Avoid ice or slippery areas.

2. Turn on the Hazard Warning Flashers.
3. Apply the parking brake.
4. Shift the transmission into Park (P).
5. Turn the ignition OFF.
6. Block both the front and rear of the wheel diagonally opposite the jacking position. For
example, if the driver’s front wheel is being
changed, block the passenger’s rear wheel.
Wheel Blocked

NOTE:
Passengers should not remain in the vehicle
when the vehicle is being raised or lifted.
JACKING INSTRUCTIONS
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 being hit when
operating the jack or changing the wheel.
WARNING!
Carefully follow these tire changing warnings
to help prevent personal injury or damage to
your vehicle:
Always park on a firm, level surface as far
from the edge of the roadway as possible
before raising the vehicle.
Turn on the Hazard Warning Flashers.
Apply the parking brake firmly and set the
transmission in PARK.
Block the wheel diagonally opposite the
wheel to be raised.
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 service center where it
can be raised on a lift.
Only use the jack in the positions indicated
and for lifting this vehicle during a tire
change.
If working on or near a roadway, be
extremely careful of motor traffic.
To assure that spare tires, flat or inflated,
are securely stowed, spares must be
stowed with the valve stem facing the
ground.

1. Remove the spare wheel, jack, and tools
from storage.

2. Using the lug wrench, loosen, but do not remove, the wheel nuts by turning them
counterclockwise one turn while the wheel
is still on the ground. Changing a dually tire
requires the lug wrench adapter.
NOTE:
If your vehicle is equipped with hub caps/wheel
covers they must be removed before raising the
vehicle off the ground. Refer to ”Hub Caps/
Wheel Covers — If Equipped” in this section.

3. Placement of the jack is critical:
CAUTION!
Do not attempt to raise the vehicle by jacking
on locations other than those indicated in the
Jacking Instructions for this vehicle.

Rear Jacking Location

Connect the extension tubes and lug
wrench.
NOTE:
If the bottle 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.
5. Remove the lug nuts and pull the wheel off. On Single Rear Wheel (SRW) trucks, install
the spare wheel and lug nuts with the cone
shaped end of the wheel nuts toward the
wheel. On 3500 Dual Rear Wheel models
(DRW) trucks, if the outer tire is being
replaced then leave the inner wheel on the
vehicle. If the inner wheel is being replaced
remove the outer wheel and replace the
inner wheel. The wheel nuts are a two-piece
assembly with a flat face. Lightly tighten the
lug nuts. To avoid the risk of forcing the
vehicle off the jack, do not fully tighten the
lug nuts until the vehicle has been lowered.

CAUTION!
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.
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.

6. Finish tightening the lug nuts. Push down on
the lug wrench while at the end of the
handle for increased leverage. Tighten the
lug nuts in a star pattern until each nut has
been tightened twice. For the correct lug nut
torque refer to “Wheel And Tire Torque
Specifications” in “Technical Specifi -
cations”. If in doubt about the correct
tightness, have them checked with a torque
wrench by an authorized dealer or service
station.
7. Install the wheel center cap and remove the 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.
Stow the replaced tire, jack, and tools as
previously described.
NOTE:
The bottle 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.
9. Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated lug nuts.
TO STOW THE FLAT OR SPARE
NOTE:
Have the flat tire repaired or replaced immedi -
ately.

1. Turn the wheel so that the valve stem is facing the ground and toward the rear of
the vehicle for convenience in checking the
spare tire inflation. Slide the wheel retainer
through the center of the wheel.

Reinstalling The Retainer

2. Lift the spare tire with one hand to give clearance to tilt the retainer at the end of
the cable and position it properly across the
wheel opening.
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.

TIRE SAFETY INFORMATION

following information: Tire Markings, Tire
Identification Numbers, Tire Terminology and
Definitions, Tire Pressures, and Tire Loading.
Tire Markings

Tire Markings

NOTE:
P (Passenger) — Metric tire sizing is based on
US design standards. P-Metric tires have the
letter “P” molded into the sidewall preceding
the size designation. Example: P215/65R15
95H.
European — Metric tire sizing is based on
European design standards. Tires designed
to this standard have the tire size molded
into the sidewall beginning with the section
width. The letter "P" is absent from this tire
size designation. Example: 215/65R15 96H.
LT (Light Truck) — Metric tire sizing is based
on US design standards. The size designation
for LT-Metric tires is the same as for P-Metric
tires except for the letters “LT” that are
molded into the sidewall preceding the size
designation. Example: LT235/85R16.
Temporary spare tires are designed for
temporary emergency use only. Temporary
high pressure compact spare tires have the
letter “T” or “S” molded into the sidewall
preceding the size designation. Example:
T145/80D18 103M.
High flotation tire sizing is based on US
design standards and it begins with the tire
diameter molded into the sidewall. Example:
31x10.5 R15 LT.
CAUTION!
Never use a floor jack directly under the
differential housing of a loaded truck or
damage to your vehicle may result.
