3. Placement of the jack:
Front Jacking Location
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.

Rear Jacking Location
When changing a rear wheel, assemble the jack drive
tube to the jack and connect the drive tube to the
extension tube. Place the jack under the axle between the
spring and the shock absorber with the drive tubes
extending to the rear.
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.Rear Jacking Location (All)

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) trucks, if the outer tire is being re-
placed 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
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 the
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 “Torque Specifications” in this
section. If in doubt about the correct tightness, have
them checked with a torque wrench by you authorized
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. Stow the
replaced tire, jack, and tools as previously described.
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.

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.

4. Rotate the wheel wrench handle clockwise 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 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.
