²For 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.²Operate the jack using the jack drive tube and the
wheel wrench. The tube extension, may be used, but
is not required.

²For 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.²For all trucks, when changing a rear wheel, as-
semble 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.

²Connect the jack tube extension and wheel wrench.
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 2500/3500 bottle jack will not lower by
turning the dial (thumbwheel) by hand, it may be neces-
sary 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 an accident. 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. Install
the spare wheel and wheel nuts with the cone shaped end
of the nuts toward the wheel on 1500/2500/3500 single
rear-wheel (SRW) models. On 3500 dual rear-wheel mod-
els (DRW) the lug nuts are a two-piece assembly with a
flat face. Lightly tighten the nuts. To avoid risk of forcing
the vehicle off the jack, do not fully tighten the nuts until
the vehicle has been lowered.
6. Using the wheel wrench, finish tightening the nuts
using a crisscross pattern. Correct nut tightness is 135 ft
lbs (183 N´m) torque for 1500/2500/3500 single-rear
wheel (SRW) models, and 145 ft lbs (197 N´m) for 3500
dual rear-wheel models. If in doubt about the correct
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 wheel center cap and remove 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
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 pryoff 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.
CAUTION!
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
lugnut 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.

8-Stud Ð 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.
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. Correct direction of rotation for dual tire instal-
lations 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 mi (160 km)
and after 500 mi (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.
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 nuts should first be firmly
seated against the wheel. The nuts should then be
432 WHAT TO DO IN EMERGENCIES
Page 435 of 554

tightened to recommended torque. Tighten the nuts to
final torque in increments. Progress around the bolt
circle, tightening the nut opposite to the nut just previ-
ously tightened until final torque is achieved. Recom-
mended torques are shown in the following chart.

To Stow The Flat Or Spare
NOTE: 1500 Regular and Quad Cabtvehicles
equipped with aluminum wheels cannot 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 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 immediately.
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.
