Tightening Wheel Lug Nuts
{WARNING:
Never use oil or grease on studs or the threads of
the wheel nuts. If you do, the wheel nuts might
come loose and the wheel could fall off, causing
a crash.
{WARNING:
Incorrect wheel nuts or improperly tightened wheel
nuts can cause the wheel to become loose and
even come off. This could lead to a crash. Be sure
to use the correct wheel nuts. If you have to
replace them, be sure to get new GM original
equipment wheel nuts. 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.
Tighten the wheel lug nuts
firmly in a crisscross
sequence as shown.
