5. The wheel wrench
has a hook that
allows you to pull
the hoist cable
towards you to
assist in reaching
the spare tire.
6. When the tire has
been lowered, tilt
the retainer (D) at
the end of the cable
so it can be pulled
up through the
wheel opening.
7. Put the spare tire near the flat tire.Use the following pictures and instructions to remove
the flat tire and raise the vehicle.
The tools you'll be using include the jack (A), the wheel
blocks (B), the jack handle (C), the jack handle
extensions (D), and the wheel wrench (E).
If the flat tire is on rear wheel of the vehicle, you'll need
to use both jack handle extensions.

If your vehicle has wheel
nut caps, loosen them by
turning the wheel wrench
counterclockwise. If you
have a center cap with
wheel nut caps, 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 out.Removing the Flat Tire and Installing the
Spare Tire
1. Use the wheel wrench to loosen all the wheel nuts.

1500 SeriesRear Position
2500 Series
On all 1500 Series vehicles, use the jacking pad
provided on the rear axle. On 2500 series vehicles,
use the axle between the spring and shock bracket.
2. Make sure the jack head is positioned so that the rear
axle is resting securely between the grooves that are
on the jack head. Turn the wheel wrench clockwise
to raise the vehicle. Raise the vehicle far enough off
the ground so there is enough room for the spare tire
to fit back underneath the rear of the vehicle.
3. Remove all the wheel
nuts and take off the
flat tire.

4. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.
CAUTION:
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after a time. The wheel could come
off and cause an accident. When you change a
wheel, remove any rust or dirt from the places
where the wheel attaches to the vehicle. In an
emergency, you can use a cloth or a paper towel
to do this; but be sure to use a scraper or wire
brush later, if you need to, to get all the rust or
dirt off.
CAUTION:
Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing a serious accident.
5. After mounting the
spare, put the wheel
nuts back on with the
rounded end of the
nuts toward the wheel.
Tighten each wheel nut
by hand. Then use the
wheel wrench until the
wheel is held against
the hub.

7. Tighten the nuts firmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come off. This could lead to an accident.
Be sure to use the correct wheel nuts. If you have
to replace them, be sure to get new GM original
equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench to
the proper torque. See ªCapacities and
Specificationsº in the Index.

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 specification.
When you reinstall the full-size wheel and tire, you
must also reinstall the wheel cover with attached plastic
nuts, the plastic nut caps or the smooth center cap.
If you are reinstalling a wheel cover with
attached plastic nuts, place it on the wheel and
tighten the nuts by hand to get them started.
Then tighten the nut caps with the wheel wrench
until they are snug. Do not overtighten the nut
caps or they may break.
If you are reinstalling plastic nut caps, tighten the
nuts by hand to get them started. Then tighten the
nut caps with the wheel wrench until they are
snug. Do not overtighten the nut caps or they
may break.
If you are reinstalling the smooth center cap,
place it on the wheel and tap it into place until it
seats flush with the wheel.
