JACKING AND TIRE CHANGING
Jack Location
• The jack and jack tools are stored under the front passenger seat.
Removal Of Jack And Tools
• To access the jack and jack tools you must remove the plastic access cover,located on the side of the seat. To remove the cover, pull the front part of the cover
(closest to the front of the seat) toward you to release a locking tab. Once the front
of the cover is loose, slide the cover toward the front of the seat until it is free from
the seat frame.
1500 Series Trucks
• Remove the jack and tool bag by removing the wing bolt and sliding the jack and tool bag from under the seat.

2500/3500 Series Trucks
• Remove the jack and tool bracket assembly by removing the wing bolt and slidingthe jack and tool bracket assembly from under the seat.
Removing The Spare Tire
• Remove the spare tire before attempting to jack up the truck. Attach the wheel wrench to the jack extension tube. Insert the tube through the access hole between
the lower tailgate and the top of the bumper and into the winch mechanism tube.
Rotate the wheel wrench handle counterclockwise until the spare tire is on the
ground with enough cable slack to allow you to pull it out from under the vehicle.
When the spare is clear, tilt the retainer at the end of the cable and pull it through
the center of the wheel.
NOTE:
Always stow the spare tire with the valve stem facing the ground.
1. Wheel Wrench
2. Spare Tire
• It is recommended that you stow the flat or spare to avoid tangling the loose
cable.
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.

Preparations
1. Park the vehicle on a firm, level surface. Avoid ice or slippery areas.
2. Turn on the Hazard Warning flasher.
3. Set the parking brake.
4. Place the shift lever into PARK. On four-wheel drive vehicles, shift the transfercase 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.
Instructions
1. Remove the spare wheel, jack, and tools from storage.
2.
Using the wheel wrench, loosen, but
do not remove, the wheel nuts by turn-
ing them counterclockwise one turn
while the wheel is still on the ground.

• Operate the jack using the jack drive tube and the wheel wrench. The tubeextension may be used but is not required.
• For 4x2 and 4x4 trucks, 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 wheel and the shock bracket with the drive tubes extending
to the rear.
• Connect the jack tube extension and wheel wrench.

2500/3500 Series Trucks
•For 2500/3500 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.

•For 2500/3500 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 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.
• For 4x2 and 4x4 trucks, 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.
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.
• By rotating the wheel wrench clock- wise, raise the vehicle until the wheel
just clears the surface.
• 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.
• Using the lug wrench, finish tightening the wheel nuts using a crisscross pattern. The correct wheel nut tightness is 130 ft lbs (175 N·m) torque (1500 Series),
135 ft lbs (183 N·m) torque for 2500/3500 single-rear wheel (SRW) models, and
140 ft lbs (190 N·m) for 3500 dual rear-wheel models. If in doubt about the
correct tightness, have them checked with a torque wrench by your authorized
dealer or at a service station.
• 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.

•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.
• Adjust the tire pressure when possible.
NOTE:
Do not oil wheel studs. For chrome wheels, do not substitute with chrome plated
wheel nuts.
Reinstalling The Jack And Tools
1500 Series Trucks
1. Tighten the jack all the way down by turning the jack turn-screw clockwise until
the jack is snug.
2. Position the jack and tool bag. Make sure the lug wrench is under the jack near the jack turn-screw.
3. Secure the tool bag straps to the jack.
4. Place the jack and tools 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.
NOTE:
Ensure that the jack slides into the
front hold down location.
