4. Raise the vehicle until the wheel just clears the
surface.
WARNING!
Raising the vehicle higher than necessary can make
the vehicle less stable. It could slip off the jack and
hurt someone near it. Raise the vehicle only enough
to remove the tire.
5. Remove the lug nuts and pull the wheel off. For
Single Rear-Wheel (SRW) models, Install the spare
wheel and lug nuts with the cone shaped end of the
nuts toward the wheel. For Dual Rear-Wheel (DRW)
models, 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 lug wrench, finish tightening the nuts
using a crisscross pattern page 333. If in doubt
about the correct tightness, have them checked with
a torque wrench by an authorized dealer or at a ser-
vice station.
WARNING!
A loose tire or jack thrown forward in a collision or
hard stop, could endanger the occupants of the
vehicle. Always stow the jack parts and the spare tire
in the places provided.
7. Install wheel center cap (if equipped) 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. Stow the
replaced tire and tools as previously described.
9. Adjust the tire pressure when possible.
10. After 25 miles (40 km), check the lug nut torque
page 333 with a torque wrench to ensure that
all lug nuts are properly seated against the wheel.
Dual Rear Wheels
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 (if equipped) 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.
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
page 333.
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
page 333.
TO STOW THE FLAT OR SPARE —
IF EQUIPPED
Refer to Upfitters Body Builder’s Guide for information
on stowing your spare tire (if equipped).
HUB CAPS/WHEEL COVERS —
IF EQUIPPED
The hub caps must be removed before raising the
vehicle off the ground.
CAUTION!
Use extreme caution when removing the front and
rear wheel covers. Damage can occur to the center
cap and/or the wheel if screwdriver type tools are
used. A pulling motion, not a pry off motion, is recom-
mended to remove the caps.
