(open end) (F) of the
extension through the
hole (G) in the rear
bumper.
Do not use the chiseled
end of the wheel wrench.
Be sure the hoist end of the extension (F) connects
to the hoist shaft (E). The ribbed square end of
the extension is used to lower the spare tire.
4. Turn the wheel wrench (H) 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 5-106.

Once the retainer is separated from the guide pin,
tilt the retainer and pull it through the center of
the wheel along with the cable and guide latch.

Removing the Flat Tire and
Installing the Spare Tire
Use the following pictures and instructions to remove
the at tire and raise the vehicle.
The tools you will be using include the jack (A), the
wheel blocks (B), the jack handle (C), the jack handle
extensions (D), and the wheel wrench (E).

2. If your vehicle has
wheel nut caps, loosen
them by turning the
wheel wrench
counterclockwise.
If the vehicle has a center cap with wheel nut caps,
the wheel nut caps are designed to stay with the
center cap after they are loosened. Remove
the entire center cap.If the wheel has a smooth center cap, place the
chisel end of the wheel wrench in the slot on
the wheel, and gently pry it out.

3. Use the wheel wrench and turn it counterclockwise
to loosen the wheel nuts. Do not remove the wheel
nuts yet.
4. Position the jack under the vehicle as shown.
If the at tire is on the front of the vehicle
(1500 Model vehicles), position the jack under
the bracket attached to the vehicle’s frame, behind
the at tire. If the at tire is on the front of the
vehicle (all other models), position the jack on
the frame behind the at tire.
Front Position - 1500 Models
5-100

If you have added a snow plow to the front of your
vehicle, lower the snow plow fully before raising
the vehicle.
Make sure that the jack head is positioned so that
the rear axle is resting securely between the
grooves that are on the jack head.
{CAUTION:
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.
{CAUTION:
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 t the jack lift
head into the proper location before raising the
vehicle.5. 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 t under the
wheel well.
6. Remove all the wheel
nuts and take off the
at tire.
5-102

{CAUTION:
Never use oil or grease on bolts or nuts because
the nuts might come loose. The vehicle’s wheel
could fall off, causing a crash.
9. Put the wheel nuts back on with the rounded end of
the nuts toward the wheel.
10. Tighten each wheel nut by hand. Then use the
wheel wrench to tighten the nuts until the wheel
is held against the hub.
11. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
{CAUTION:
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.
5-104

{CAUTION:
Incorrect or improperly tightened wheel nuts can
cause the wheel to come loose and even come
off. This could lead to a crash. If you have to
replace them, be sure to get new original
equipment wheel nuts. Stop somewhere as soon
as you can and have the nuts tightened with a
torque wrench to the proper torque specication.
SeeCapacities and Specifications on page 5-129
for wheel nut torque specication.
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 5-129for the wheel nut
torque specication.12. Tighten the nuts rmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
When you reinstall the regular wheel and tire, you must
also reinstall either the center cap, or bolt-on hub cap,
depending on what your vehicle is equipped with. For
center caps, place the cap on the wheel and tap it into
place until it seats ush with the wheel. The cap only
goes on one way. Be sure to line up the tab on the center
cap with the indentation on the wheel. For bolt-on hub
caps, align the plastic nut caps with the wheel nuts and
then tighten by hand. Then use the wheel wrench to
tighten.

Secondary Latch System
Your vehicle has an underbody-mounted tire hoist
assembly equipped with a secondary latch system.
It is designed to stop the spare tire from suddenly falling
off your vehicle. For the secondary latch to work, the
spare must be installed with the valve stem pointing
down. SeeStoring a Flat or Spare Tire and Tools on
page 5-109.
{CAUTION:
Before beginning this procedure read all the
instructions. Failure to read and follow the
instructions could damage the hoist assembly and
you and others could get hurt. Read and follow the
instructions listed next.To release the spare tire from the secondary latch:
1. Check under the
vehicle to see if the
cable end is visible.
If the cable is not
visible proceed
to Step 6.
2. If it is visible, rst try to tighten the cable by turning
the wheel wrench clockwise until you hear two clicks
or feel it skip twice. You cannot overtighten the cable.
3. Loosen the cable by turning the wrench
counterclockwise three or four turns.
4. Repeat this procedure at least two times. If the spare
tire lowers to the ground, continue with Step 5 of
Removing the Spare Tire and Tools on page 5-93.
5. If the spare does not lower, turn the wrench
counterclockwise until approximately 6 inches
(15 cm) of cable is exposed.
6. Stand the wheel blocks on their shortest ends, with
the backs facing each other.
