{Warning
Wheel nuts that are not tight can
work loose. If all the nuts on a
wheel come off, the wheel can
come off the vehicle, causing a
crash. All wheel nuts must be
properly tightened. Follow the
rules in this section to be sure
they are.
{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(Continued)
Warning (Continued)
after replacing. Follow the torque
specification supplied by the
aftermarket manufacturer when
using accessory locking wheel
nuts. SeeCapacities and
Specifications 0311 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
torque specification. See
Capacities and Specifications
0 311 for the wheel nut torque
specification.

wheel wrench clockwise and in
a crisscross sequence, as
shown.
12. Put the wheel cover or the center cap and plastic wheel
nut caps back on. Remove any

Have a technician check the
wheel nut tightness of all
wheels with a torque wrench
after the first 160 km (100 mi)
and then 1 600 km (1,000 mi)
after that. Repeat this service
whenever a tire is removed or serviced. See
Capacities and
Specifications 0311 for more
information.
