wheel GMC SIERRA 2010 Owner's Manual

8. Remove any rust or dirtfrom the wheel bolts,
mounting surfaces, and
spare wheel.
9. Install the spare tire.
{WARNING:
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.
10. Put the wheel nuts back on with the rounded end of the nuts toward the wheel.
11. Tighten each wheel nut by hand. Then use the wheel wrench to tighten the nuts until the wheel is
held against the hub.
12. Turn the wheel wrench counterclockwise to lower the vehicle. Lower the jack completely.
{WARNING:
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.

{WARNING:
Wheel nuts that are improperly or incorrectly
tightened can cause the wheels to become loose
or come off. The wheel nuts should be tightened
with a torque wrench to the proper torque
specification after replacing. Follow the torque
specification supplied by the aftermarket
manufacturer when using accessory locking wheel
nuts. SeeCapacities and Specifications
on
page 6‑126
for original equipment wheel nut
torque specifications.
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. See Capacities and
Specifications
on page 6‑126for the wheel nut
torque specification.
13. Tighten the nuts firmly in a crisscross sequence as
shown by turning the wheel wrench clockwise.
Have a technician check the wheel nut tightness of all
wheels with a torque wrench after the first 100 miles
(160 km) and then 1,000 miles (1600 km) after that.
Repeat this service whenever you have a tire removed
or serviced. See Capacities and Specifications
on
page 6‑126for more information.
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.
6-102

For center caps, place the cap on the wheel and tap it
into place until it seats flush 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
This vehicle may have 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 6‑106.
{WARNING:
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, first 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 6‑92.
6-103

5. If the spare does not lower, turn the wrenchcounterclockwise 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 edgeof the jack (A) on the
wheel blocks (B),
separating them so that
the jack is balanced
securely.
8. Attach the jack handle, extension, and wheelwrench to the jack and place it (with the wheel
blocks) under the vehicle toward the front of the
rear bumper.
6-104

9. Position the center lift point of the jack under thecenter of the spare tire.
10. Turn the wrench clockwise to raise the jack until it lifts the end fitting.
11. Continue raising the jack until the spare tire stops moving upward and is held firmly 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.
{WARNING:
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 firmly 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 flat tire using the
hoist assembly until it has been inspected and/or
replaced.

Spare Tire
Your vehicle, when new, had a fully-inflated spare tire.
A spare tire may lose air over time, so check its inflation
pressure regularly. See Inflation - Tire Pressure
on
page 6‑72and Loading the Vehicleon page 5‑30for
information regarding proper tire inflation and loading
your vehicle. For instruction on how to remove, install or
store a spare tire, see Removing the Flat Tire and
Installing the Spare Tire
on page 6‑97and Storing a
Flat or Spare Tire and Tools on page 6‑106. Notice:
If the vehicle has four-wheel drive and the
different size spare tire is installed on the vehicle,
do not drive in four-wheel drive until you can have
your flat tire repaired and/or replaced. You could
damage the vehicle, and the repair costs would not
be covered by your warranty. Never use four-wheel
drive when the different size spare tire is installed
on the vehicle.
Your vehicle may have a different size spare tire than
the road tires originally installed on your vehicle. This
spare tire was developed for use on your vehicle, so it
is all right to drive on it. If your vehicle has four-wheel
drive and the different size spare tire is installed, keep
the vehicle in two-wheel drive.
After installing the spare tire on your vehicle, you should
stop as soon as possible and make sure the spare tire
is correctly inflated. Have the damaged or flat road tire
repaired or replaced as soon as you can and installed
back onto your vehicle. This way, the spare tire will be
available in case you need it again.
Do not mix tires and wheels of different sizes, because
they will not fit. Keep your spare tire and its wheel
together. If your vehicle has a spare tire that does not
match your vehicle's original road tires and wheels
in size and type, do not include the spare in the
tire rotation.

chrome-plated wheels. The surface of these wheels is similar to the painted
surface of the vehicle. Do not use strong soaps,
chemicals, abrasive polishes, abrasive cleaners,
cleaners with acid, or abrasive cleaning brushes on
them because they could damage the surface.
Do not use chrome polish on aluminum wheels.
Notice:
Using chrome polish on aluminum wheels
could damage the wheels. The repairs would not be
covered by the vehicle warranty. Use chrome polish
on chrome wheels only.
Use chrome polish only on chrome-plated wheels, but
avoid any painted surface of the wheel, and buff off
immediately after application.
Notice: Driving the vehicle through an automatic
car wash that has silicone carbide tire cleaning
brushes, could damage the aluminum or
chrome-plated wheels. The repairs would not be
covered by the vehicle warranty. Never drive a
vehicle that has aluminum or chrome-plated wheels
