5. Remove the lug nuts and pull the wheel off.
Install the spare wheel and lug nuts with the
cone shaped end of the nuts toward the
wheel on Single Rear-Wheel (SRW) models.
On Dual Rear-Wheel models (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 lug wrench, finish tightening the nuts using a crisscross pattern
Úpage 432. If in doubt about the correct
tightness, have them checked with a torque
wrench by an authorized dealer or at a
service station. 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. If the jack will not lower by turning the dial
(thumbwheel) by hand, it may be necessary
to use the jack driver in order to lower the
jack. Stow the replaced tire, jack, and tools
as previously described.
9. Adjust the tire pressure when possible.
10. After 25 miles (40 km), check the lug nut torque Úpage 432 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 assembling 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 correctly 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 loca-
tion. 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 Ú page 432.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.
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.
