1. Assemble the wheel wrench (G) to one or two of
the jack handle extensions and the hoist extension.
Insert the hoist extension end through the hole
in the rear bumper.
2. Be sure the hoist extension end connects to the
hoist shaft (E). The chiseled end of the extension
is used to lower the spare tire.
3. Turn the wheel wrench counterclockwise to lower
the spare tire to the ground. Continue to turn the
wheel wrench until the spare tire can be pulled out
from under the vehicle.
If the spare tire does not lower to the ground, the
secondary latch is engaged causing the tire not to
lower. SeeSecondary Latch System on page 6-97.4. When the tire has been lowered, pull the tire toward
you so you can reach the tire retainer and pull it up
through the wheel opening.
If you have a vehicle which was completed from
a cab and chassis, refer to the information
from body supplier/installer.
The spare tire is a full-size tire, like the other tires
on the vehicle.
5. Put the spare tire near the flat tire.

Removing the Flat Tire and
Installing the Spare Tire
If your vehicle has plastic wheel nut caps, loosen
them by turning the wheel wrench counterclockwise.
The wheel nut caps are designed to remain with
the center cap. Remove the center cap.
If the wheel has a smooth center piece, place the chisel
end of the wheel wrench in the slot on the wheel and
gently pry it out.
1. Do a safety check before proceeding. SeeChanging
a Flat Tire on page 6-86for more information.
2. Loosen all the wheel nuts with the wheel wrench.
Do not remove them yet.3. Assemble the jack and tools:
Front Flat:Assemble the jack (A) together with the
jack handle (B), 1 or 2 jack handle extensions (D)
and the wheel wrench (E).
Rear Flat:Assemble the jack (A) together with the
jack handle (B), 2 jack handle extensions (D),
and the wheel wrench (E).

{WARNING:
Getting under a vehicle when it is jacked up is
dangerous. If the vehicle slips off the jack you
could be badly injured or killed. Never get under
a vehicle when it is supported only by a jack.
{WARNING:
Raising your vehicle with the jack improperly
positioned can damage the vehicle and even make
the vehicle fall. To help avoid personal injury and
vehicle damage, be sure to fit the jack lift head into
the proper location before raising the vehicle.5. Raise the vehicle by turning the wheel wrench
clockwise. Raise the vehicle far enough off the
ground so there is enough room for the spare
tire to fit.
6. Remove all the
wheel nuts.
7. Take flat tire off of the mounting surface.

9. Put the wheel nuts
back on with the
rounded end of the
nuts toward the wheel.
Tighten each wheel
nut by hand until
the wheel is held
against the hub.
10. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
{WARNING:
Wheel nuts that are not tight can work loose. If all
the nuts on a wheel come off, the wheel can come
off the vehicle, causing a crash. All wheel nuts
must be properly tightened. Follow the rules in this
section to be sure they are.
{WARNING:
If wheel studs are damaged, they can break. If all
the studs on a wheel broke, the wheel could come
off and cause a crash. If any stud is damaged
because of a loose-running wheel, it could be that
all of the studs are damaged. To be sure, replace
all studs on the wheel. If the stud holes in a wheel
have become larger, the wheel could collapse in
operation. Replace any wheel if its stud holes have
become larger or distorted in any way. Inspect hubs
and hub-piloted wheels for damage. Because of
loose running wheels, piloting pad damage may
occur and require replacement of the entire hub, for
proper centering of the wheels. When replacing
studs, hubs, wheel nuts or wheels, be sure to use
GM original equipment parts.

{WARNING:
Wheel nuts that are improperly or incorrectly
tightened can cause the wheels to become loose or
come off. The wheel nuts should be tightened with
a torque wrench to the proper torque specification
after replacing. Follow the torque specification
supplied by the aftermarket manufacturer when
using accessory locking wheel nuts. SeeCapacities
and Specications on page 6-116for original
equipment wheel nut torque specifications.
Notice:Improperly tightened wheel nuts can lead
to brake pulsation and rotor damage. To avoid
expensive brake repairs, evenly tighten the wheel
nuts in the proper sequence and to the proper
torque specication. SeeCapacities and
Specifications on page 6-116for the wheel nut
torque specication.11. Use the wheel wrench to tighten the nuts firmly.
Turn the wheel wrench clockwise and in a
crisscross sequence as shown.
12. Put the wheel cover or the center cap and plastic
wheel nut caps back on. Remove any wheel blocks.
Have a technician check the wheel nut tightness
of all wheels with a torque wrench after the first
100 miles (160 km) and then 1,000 miles (1600 km)
after that. Repeat this service whenever you have
a tire removed or serviced. SeeCapacities and
Specications on page 6-116for more information.
