2009 GMC YUKON clock

Rear Tire Flat:If the at tire is on a rear tire of the
vehicle, you will need to use the jack handle (B) and
both jack handle extensions (C). Attach the wheel
wrench (D) to the jack handle extensions (C). Attach
the jack handle (B) to the jack (A). Use the jacking
pad provided on the rear axle. Turn the wheel
wrench (D) clockwise to raise the vehicle. Raise the
vehicle far enough off the ground so there is enough
room for the spare tire to clear the ground.
{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. Rear Position – All Other Models

wheel wrench to tighten the nuts until the wheel
is held against the hub.
10. Turn the wheel wrench counterclockwise to lower
the vehicle. Lower the jack completely.
11. Tighten the nuts rmly in a crisscross sequence as

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 5-123
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 5-123for the wheel nut torque specication.
When you reinstall the regular wheel and tire, you must
also reinstall either the center cap or the bolt-on hub
cap, depending on which your vehicle has.
For center caps, line up the tab on the center cap
with the slot in the wheel. The cap only goes in
one way. Place the cap on the wheel and press until
it snaps into place.
For bolt-on hub caps, line up the plastic nut caps
with the wheel nuts and tighten clockwise by
hand to get them started. Then tighten with the
wheel wrench until snug.

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. See
Storing a Flat or Spare Tire and Tools on page 5-103.
{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 5-89.

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.
5-101

9. Position the center lift point of the jack under the
center of the spare tire.
10. Turn the wrench clockwise to raise the jack until it
lifts the end tting.
11. Continue raising the jack until the spare tire stops
moving upward and is held rmly in place. The
secondary latch has released and the spare tire is
balancing on the jack.
12. Lower the jack by turning the wheel wrench
counterclockwise. Keep lowering the jack until
the spare tire slides off the jack or is hanging by
the cable.
{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 under the spare.
13. Disconnect the jack handle from the jack and
carefully remove the jack. Use one hand to push
against the spare while rmly pulling the jack out
from under the spare tire with the other hand.
If the spare tire is hanging from the cable, insert the
hoist end of extension, and wheel wrench into the
hoist shaft hole in the bumper and turn the wheel
wrench counterclockwise to lower the spare the rest
of the way.
14. Turn the wheel wrench in the hoist shaft hole in the
bumper clockwise to raise the cable back up if the
cable is hanging under the vehicle.
Have the hoist assembly inspected as soon as you can.
You will not be able to store a spare or at tire using the
hoist assembly until it has been inspected and/or
replaced.
To continue changing the at tire, seeRemoving the
Flat Tire and Installing the Spare Tire on page 5-94.

vehicle by turning the wheel wrench clockwise
until you hear two clicks or feel it skip twice. You
cannot overtighten the cable.7. Make sure the tire is stored securely. Push, pull (A),
