Remove the jack and tools from the bracket assembly.
Turn the jack-turn-screw counterclockwise to release jack
from bracket assembly.WARNING!
After using the jack and tools, always reinstall them
in the original carrier and location. While driving
you may experience abrupt stopping, rapid accelera-
tion or sharp turns. A loose jack, tools, bracket or
other objects in the vehicle may move around with
force, resulting in serious injury.
Removing The Spare Tire
1. Remove the spare tire before attempting to jack up thetruck. 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 be-
tween the lower tailgate and the top of the bumper
and into the winch mechanism tube.

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.Jack Instructions (2500, 3500 Series)
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 flasher.
• Block the wheel diagonally opposite the wheel to
be raised.
• Set the parking brake firmly and set an automatic
transmission in PARK; a manual transmission in
REVERSE.
• Never start or run the engine with the vehicle on a
jack.

WARNING!(Continued)
•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.
CAUTION!
Do not attempt to raise the vehicle by jacking on
locations other than those indicated in the Jacking
Instructions for this vehicle.
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.

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. Onsingle 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.

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.
