GMC Sierra Classic 2007 Owner's Manual page 575

CAUTION:
{
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the wheel
to come 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
the proper torque specification. See
Capacities and Specifications on page 605
for wheel nut torque specification.
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 605 for
the wheel nut torque specification.
12. Tighten the nuts firmly in a crisscross
sequence as shown by turning the wheel
wrench clockwise.
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. 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.
