Connect the jack tube extension and wheel wrench.
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.
NOTE: If the bottle 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. On
single rear-wheel (SRW) trucks, install the spare wheel
and wheel nuts with the cone shaped end of the wheel
nuts toward the wheel. On 3500 dual rear-wheel
models (DRW) the wheel nuts are a two-piece assem-
bly with a flat face. Lightly tighten the wheel nuts. To
avoid the risk of forcing the vehicle off the jack, do not
fully tighten the wheel nuts until the vehicle has been
lowered.

6. Finish tightening the lug nuts. Push down on thewrench 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 “Torque Specifications” in this
section. If in doubt about the correct tightness, have

dealer or service station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Al-
ways stow the jack parts and the extra tire and wheel
in the places provided.
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. If the bottle 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. Stow the replaced tire, jack,
and tools as previously described. 9. Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do
not substitute with chrome plated wheel nuts.To Stow The Flat Or Spare
NOTE: Have the flat tire repaired or replaced immedi-
ately.
WARNING!
A loose tire thrown forward in a collision or hard
stop could injure the occupants in the vehicle. Have
the deflated (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 conve-
nience in checking the spare tire inflation. Slide the
wheel retainer through the center of the wheel.

2. Lift the spare tire with one hand to give clearance totilt the retainer at the end of the cable and position it
properly across the wheel opening. 3. Attach the wheel wrench to the jack extension tube
with the curved angle facing away from the vehicle.
Insert the tube through the access hole between the
lower tailgate and the top of the bumper and into the
winch mechanism tube.

4. Rotate the lug wrench handle clockwise until thewheel is drawn into place against the underside of the
vehicle. Continue to rotate until you feel the winch mechanism slip, or click three or four times. It cannot
be overtightened. Push against the tire several times to
ensure it is firmly in place.

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.
Reinstalling The Jack And Tools (2500 And 3500
Series)
1. Tighten the jack all the way down by turning the jack turn-screw counterclockwise until the jack is snug.
2. Position the jack and tools into bracket assembly. Make sure the lug wrench is under the jack near the
jack turn-screw. Snap tools into bracket assembly clips.
Install the jack into bracket assembly and turn the
jack-turn-screw clockwise until jack is snug into
bracket assembly. 3. Place the jack and tool bracket assembly in the storage
position holding the jack by the jack turn-screw, slip
the jack and tools under the seat so that the bottom slot
engages into the fastener on the floor.

CAUTION!
Use extreme caution when removing the front and
rear center caps. 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 recom-
mended to remove the caps.
For single rear wheel (SRW) models, use the flat blade on
the end of the lug wrench to pull the hub cap off. Insert
the blade end into the pull off notch and carefully pull the
hub cap off with a back and forth motion.
On 3500 models with dual rear wheels (DRW), you must
first remove the hub caps. The jack handle driver has a
hook at one end that will fit in the pull off notch of the
rear hub caps. Position the hook and pull straight out on
the ratchet firmly. The hub cap should pop off. The wheel
skins can now be removed. For the front hub cap, use the flat blade on the end of the lug wrench to pull the caps
off. The wheel skin can now be removed.
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.
You must use the flat end of the lug wrench to pull off the
wheel skins. Locate the hub cap pull notches (2 notches
on each cap). Insert the flat tip completely and using a
back and forth motion, loosen the wheel skin. Repeat this
procedure around the tire until the skin pops off.
