Jacking and tire changing
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.
Being under a jacked-up vehicle is dangerous. The vehicle could slip off the jack and fall on you. You could be crushed. Never put any part of your body under a vehicle that is on a jack.
Never start or run the engine while the vehicle 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.

WARNING! (Continued)
The jack is designed to be used as a tool for
changing tires only. The jack should not be used to lift the vehicle for service purposes. The vehicle should be jacked on a firm level surface only. Avoid ice or slippery areas.
Jack Location
The jack and jack tools are stored under the front passenger seat.
Removal
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.
Remove the jack and tools by removing the wing bolt and sliding the 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 coun- terclockwise 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.

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.
4X4 Jacking Location
Rear Jacking Location
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.
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.
4x4 Jacking Location
Rear Jacking Location (All)
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 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. Using the wheel wrench, finish tightening the wheel nuts using a crisscross pattern. The correct wheel nut tightness is 130 ft lbs (177 N·m) torque (1500 Series), 135 ft lbs (183 N·m) torque for 2500/3500 single-rear wheel (SRW) models, and 145 ft lbs (197 N·m) for 3500 dual rear-wheel models. If in doubt about the correct tight- ness, 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.
Hub Caps/Wheel Covers If Equipped
The hub caps must be removed before raising the vehicle off the ground. For 2500/3500 single rear-wheel (SRW) models, use the blade on the end of the lug wrench to pry the hub cap off. Insert the blade end into the pry-off notch and carefully pop off the hub cap with a back-and-forth motion. On 3500 models with dual rear wheels (DRW), you must first remove the hub caps. The jack handle driver has a hook at one end that will fit in the pry off notch of the rear hub caps. Position the hook and pull out on the ratchet firmly. The hub cap should pop off. The wheel skins can now be removed. For the front hub cap on 3500 models use the blade on the end of the lug wrench to pry the caps off. The wheel skin can now be removed.
CAUTION!
Use a back-and-forth motion to remove the hub
cap. Do not use a twisting motion when removing the hub cap, damage to the hub cap finish may occur.
The rear hub caps on the dual rear wheel has two pry-off notches. Make sure that the hook of the jack handle driver is located squarely in the cap notch before attempting to pull off.
You must use the flat end of the lug wrench to pry off the wheel skins. Insert the flat tip completely and using a back-and-forth motion, loosen the wheel skin. Repeat this procedure around the tire until the skin pops off. Replace the wheel skins first using a rubber mallet. When replacing the hub caps, tilt the cap retainer over the lug
nut bolt circle and strike the high side down with a rubber mallet. Be sure that the hub caps and wheel skins are firmly seated around the wheel.
Wheel Nuts
All wheel nuts should be tightened occasionally to elimi- nate the possibility of wheel studs being sheared or the bolt holes in the wheels becoming elongated. This is especially important during the first few hundred miles/ kilometers of operation to allow the wheel nuts to become properly set. All wheel nuts should first be firmly seated against the wheel. The wheel nuts should then be tightened to recommended torque. Tighten the wheel nuts to final torque in increments. Progress around the bolt circle, tightening the wheel nut opposite to the wheel nut just previously tightened until final torque is achieved. Recommended torques are shown in the fol- lowing chart.
8-Stud Dual Rear Wheels
Dual wheels are flat-mounted and center-piloted. The lug nuts are a two-piece assembly. When the tires are being rotated or replaced, clean these lug nuts and add two drops of oil at the interface between the hex and the washer.
Slots in the wheels will assist in properly orienting the inner and outer wheels. Align these slots when assem- bling the wheels for best access to the tire valve on the inner wheel. The tires of both dual wheels must be completely off the ground when tightening, to ensure wheel centering and maximum wheel clamping.
Oiling Location
Dual wheel models require a special heavy-duty lug nut tightening adapter (included with the vehicle) to cor- rectly tighten the lug nuts. Also, when it is necessary to remove and install dual rear wheels, use a proper vehicle lifting device.
NOTE: When installing a spare tire as part of a dual rear wheel end combination, the tire diameter of the two individual tires must be compared. If there is a significant difference, the larger tire should be installed in a front location. The correct direction of rotation for dual tire installations must also be observed.
These dual rear wheels should be tightened as follows:
1. Tighten the wheel nuts in the numbered sequence to a snug fit. 2. Retighten the wheel nuts in the same sequence to the torques listed in the table. Go through the sequence a second time to verify that specific torque has been achieved. Retighten to specifications at 100 miles (160 km) and after 500 miles (800 km). It is recommended that wheel stud nuts be kept torqued to specifications at all times. Torque wheel stud nuts to specifications at each lubrication interval.
Tightening Pattern
To Stow The Flat Or Spare NOTE: Vehicles equipped with aluminum wheels can- not be stored under the vehicle because the wheel retainer will not fit through the wheel pilot hole. Secure the flat tire in the bed of the truck.
Have the flat tire repaired or replaced immediately.
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.
Turn the wheel so that the valve stem is down. Slide the wheel retainer through the center of the wheel and position it properly across the wheel opening. For convenience in checking the spare tire inflation, stow with the valve stem toward the rear of the vehicle. Attach the wheel wrench to the extension tube. Rotate the winch mechanism 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 be sure it is firmly in place.
HOISTING
A conventional floor jack may be used at the jacking locations. Refer to the graphics that show jacking loca- tions. However, a floor jack or frame hoist must never be used on any other parts of the underbody.
CAUTION! Never use a floor jack directly under the differential housing of a loaded truck or damage to your vehicle may result.
