K. Hoist EndFollow these instructions to lower the spare tire:
1. Your vehicle is equipped with a hoist lock. Open the
spare tire lock cover on the bumper and use the
ignition key to remove the lock.
2. Assemble the wheel wrench and the two jack handle
extensions as shown. Insert the hoist end (open end)
of the extension through the hole in the rear bumper.
Be sure the hoist end of the extension connects into
the hoist shaft.
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. The wheel wrench has a
hook that allows you to pull the hoist cable towards
you, to assist in reaching the spare tire.
4. When the tire has been lowered, tilt the retainer at
the end of the cable so it can be pulled up through
the wheel opening.
5. Put the spare tire near the flat tire.

The tools you'll be using include the bottle 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 a rear tire of the vehicle, you'll need
to use both jack handle extensions.Attach the wheel wrench to the jack handle extensions
(as needed). Attach the jack handle to the jack.

Turn the wheel wrench clockwise to raise the jack lift
head a little.
To remove the center cap
place the chisel end of the
wheel wrench in the slot
on the wheel and gently
pry out.

5-24 Removing the Flat Tire and Installing the
Spare Tire
1. Use the wheel wrench to
loosen all the wheel
nuts. Turn the wheel
wrench
counterclockwise to
loosen the wheel nuts.
Don't remove them yet.
2. Position the jack under the vehicle. If the flat tire is
on the front of the vehicle, position the jack on the
frame behind the flat tire.
If the flat tire is on the rear, position the jack under
the rear axle between the spring anchor and the
shock absorber bracket.
NOTICE:
If your vehicle is equipped with
QUADRASTEER
avoid contact with tie rods
and tire rod boots when jacking the vehicle.

Rear Position
3. 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 under the wheel well.
4. Remove all the wheel
nuts and take off the
flat tire.
5. Remove any rust or dirt
from the wheel bolts,
mounting surfaces and
spare wheel.

5-27
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.
6. 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. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.

5-29
8. 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 center cap. Place the cap on the
wheel and tap it into place until it seats flush with
the wheel.
