Preparations
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. Apply the parking brake.
4. Place the gear selector into PARK. On four-wheel drive vehicles, shift the transfer case to the 4L position.
5. Turn the ignition OFF.
Block both the front and rear of the wheel diagonally
opposite the jacking position. For example, if the right front
wheel is being changed, block the left rear wheel. NOTE:Passengers should not remain in the
vehicle when the vehicle is being jacked.

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 ve- hicle until the wheel just clears the surface.
WARNING!
Raising the vehicle higher than necessary can make the
vehicle unstable. 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) 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 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 them checked
with a torque wrench by you authorized dealer or
service station.

A loose tire or jack thrown forward in a collision or
hard stop could injure someone in the vehicle. Always
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.
