3. Turn the ratchet counterclockwise to lower the
spare tire to the ground. 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 371.4. 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
the body supplier/installer.
The spare tire is a full-size tire, like the other tires
on your vehicle.

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. With the DOWN side facing you, use the
ratchet and wheel wrench to loosen all the
wheel nuts. Do not remove them yet.2. Assemble the jack and tools for a front or rear
flat as follows:
Front Flat:Assemble the jack (A) together
with the jack handle (B) and ratchet (C)
as shown. Be sure that the ratchet has the
UP mark facing you.

{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.
4. Raise the vehicle by turning the ratchet
clockwise. Make sure the UP mark faces you.
Raise the vehicle far enough off the ground
so there is enough room for the spare
tire to fit.
368

{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.
8. 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.
9. Lower the vehicle by turning the jack handle
counterclockwise. Lower the jack completely.
{CAUTION:
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the wheel
to come 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 specication. See
Capacities and Specifications on page 393
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. See
Capacities and Specifications on page 393for
the wheel nut torque specication.

10. Use the wheel wrench to tighten the nuts
firmly. Turn the wheel wrench clockwise
and in a crisscross sequence as shown.
11. Put the wheel cover or the center cap and
plastic wheel nut caps back on. Remove
any wheel blocks.
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 the vehicle if the cable
holding the spare tire is damaged. For the
secondary latch to work, the tire must be stowed
with the valve stem pointing down.
SeeStoring a Flat or Spare Tire and Tools on
page 375for instructions on storing the spare tire
correctly.
{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.
371

To release the spare tire from the secondary latch,
do the following:
{CAUTION:
Someone standing too close during the
procedure could be injured by the jack.
If the spare tire does not slide off the jack
completely, make sure no one is behind
you or on either side of you as you pull
the jack out from the under spare.1. Check under the
vehicle to see if the
cable end is visible.
If the cable is not visible, start this procedure
at Step 6.
2. Turn the wrench counterclockwise until
approximately 6 inches (15 cm) of cable
is exposed.
372

3. Connect the jack handle (C) and jack handle
extension (B) together and press the retention
clip (arrow) so it engages.
4. Attach the jack handle/jack handle extension
to the jack. With the UP mark facing you,
slide the ratchet onto the end of the jack
handle extension. The set-up should look like
the picture above.5. Place the jack under the vehicle, ahead of the
rear bumper. Position the center lift point of
the jack under the center of the spare tire and
turn the handle clockwise to raise the jack
until it lifts the secondary latch spring.
6. Keep raising the jack until the spare tire stops
moving upward and is held firmly in place.
This lets you know that the secondary
latch has released. The spare tire is now
balancing on the jack.
373

7. Lower the jack by turning the ratchet
counterclockwise. Keep lowering the jack
until the spare tire slides off the jack or
is hanging by the cable.
8. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to
push against the spare while firmly pulling the
jack out from under the spare tire with the
other hand.
If the spare tire is hanging from the cable,
slide the ratchet onto the wheel wrench and
insert the wheel wrench into the hoist
shaft hole above the bumper. Turn the wheel
wrench counterclockwise to lower the spare
the rest of the way. Be sure the DOWN mark
on the ratchet is facing you.
9. Tilt the retainer at the end of the cable and
pull it through the wheel opening. Pull the
tire out from under the vehicle.Notice:If you drive away before the spare
tire or secondary latch system cable has been
reinstalled, you could damage your vehicle.
Always reinstall this cable before driving
your vehicle.
10. If the cable is hanging under the vehicle, turn
the wheel wrench in the hoist shaft hole in the
bumper clockwise to raise the cable back up.
Have the hoist assembly inspected as soon as
you can. You will not be able to store a spare or
flat tire using the hoist assembly until it has
been repaired or replaced.
To continue changing the flat tire, return to Step 4
ofRemoving the Flat Tire and Installing the
Spare Tire on page 365.
