CAUTION:
Incorrect wheel nuts or improperly tightened
wheel nuts can cause the wheel to become loose
and even come
off.
This could lead to an accident.
Be sure to use the correct wheel nuts. If you have
to replace them, be sure to get new GM original
equipment wheel nuts.
Stop somewhere as soon as you can and have
the nuts tightened with a torque wrench
to
140
lb-ft
(190
Nmm).
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.
Put the wheel cover back on, if you have one.
Remove any wheel blocks.
Remember that the jack, jacking equipment and tire
must be properly stored in their original storage
position before you begin driving again. The next
part will show you how.
