GMC 2008 Envoy - Manual (Page 385)

{ 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 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 5-120 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 5-120 for the wheel nut torque specification.
14. Use the wrench to
tighten the wheel nuts
firmly in a crisscross
sequence as shown.
