The tools you will be using include
the jack (1), the wheel blocks (2),
the jack handle (3), the jack handle
extensions (4), and the wheel
wrench (5).1. Do a safety check before proceeding. See If a Tire Goes
Flat 0408.
2. If the 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.

Rear Position–All Other Models
For all other models, position
the jack under the rear axle
between the spring anchor and
the shock absorber bracket.
If a snow plow has been added
to the front of the 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.
{Warning
Getting under a vehicle when it is
lifted on a jack 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.
{Warning
Raising the 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 fit the jack lift
head into the proper location
before raising the vehicle.
6. 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 fit under the wheel well.
7. Remove all the wheel nuts andtake off the flat tire.
{Warning
Rust or dirt on a wheel, or on the
parts to which it is fastened, can
make wheel nuts become loose
after time. The wheel could come
off and cause an accident. When
changing a wheel, remove any
rust or dirt from places where the
wheel attaches to the vehicle. In
an emergency, a cloth or a paper

towel can be used; however, use
a scraper or wire brush later to
remove all rust or dirt.
8. Remove any rust or dirt fromthe 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.
(Continued)
Warning (Continued)
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 0457 for original
equipment wheel nut torque
specifications.
Caution
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

Caution (Continued)
torque specification. See
Capacities and Specifications
0457 for the wheel nut torque
specification.
13. Tighten the nuts firmly in a crisscross sequence, as
shown, by turning the wheel
wrench clockwise.
For vehicles with dual wheels, have
a technician check the wheel nut
tightness of all wheels with a torque
wrench after the first 160, 1 600 and
10 000 km (100, 1,000 and 6,000 mi).
Repeat this service whenever you have a tire removed or serviced.
See
Capacities and Specifications
0 457.
When reinstalling the regular wheel
and tire, also reinstall either the
center cap, or bolt-on hub cap,
depending on what the vehicle is
equipped with. 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.
