2008 GMC CANYON lock

For regular and extended
cab vehicles, the jack and
wheel blocks are located
under the cover at the
center of the vehicle
behind the front seats.
To access the tools:
1. Move the seats forward
to access the cover.2. Turn the wing nut on the cover counterclockwise
to remove it.
For crew cab models, reach under the rear seat
to access the jack and wheel blocks. To reinstall
the jack and wheel block assembly in the mounting
bracket, insert the tabs into the jack base by
pushing the blocks up into the assembly. The outer
hole in the jack base aligns with the tab on the
bracket. When reinstalling, make sure the jack
is secure, but do not overtighten the jack in
the bracket.
3. Remove the wheel blocks and the wheel block
retainer by turning the wing nut counterclockwise.
4. Put the wheel blocks at the front and rear of the tire
farthest away from the one being changed. That
would be the tire on the other side, at the opposite
end of the vehicle.
5. Locate the wing nut used to retain the storage bag
and tools which is under the front passenger’s seat.
Remove it by turning the wing nut counterclockwise.
Use the jack handle extensions and the wheel wrench
to remove the underbody-mounted spare tire. Regular/Extended Cab

1. Assemble the wheel wrench (D) and the jack
handle extensions (A).2. Insert the hoist end (chiseled end) of the extension
tool (C) through the hole in the rear bumper and
into the funnel-shaped guide. The chiseled end of
the extension is used to lower the spare tire.
3. Turn the wheel wrench (D) 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 5-91.

the vehicle. Lower the jack completely.
{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 5-116for 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 5-116for the wheel
nut torque specication. Rear Position

12. Tighten the wheel 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 the center cap. 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.
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 5-94.
{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 5-81.
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.
7. Place the bottom
edge of the jack (A) on
the wheel blocks (B),
separating them so
that the jack is
balanced securely.8. Attach the jack handle, extension, and wheel wrench
to the jack and place it (with the wheel blocks) under
the vehicle toward the front of the rear bumper.
