4x2 Series Trucks Front Jacking Location
For 2500 and 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.
Operate the jack using the jack drive tube and the wheel
wrench. The tube extension, may be used, but is not
required.4x4 Series Trucks Front Jacking Location
For 2500 and 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

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. Using the lug wrench, finish tightening the wheel nuts using a crisscross pattern. The correct wheel nut
tightness for a cone type wheel nut is 120–140 ft lbs
(160–190 N·m) torque, for a flanged type wheel nut is
130–160 ft lbs (175–215 N·m) torque. If in doubt about
the correct tightness, have them checked with a torque
wrench by your authorized 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. 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 theground 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 to tilt 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.
