CAUTION:
{
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.

Magnesium Wheels
Notice: If your vehicle has magnesium wheels,
moisture on or around the mounting surface of the
magnesium wheel will cause corrosion and damage
to the wheel. To help prevent this, a magnesium
wheel uses two rubber O-rings. One goes on the
inboard side of the wheel and the other on the back
of the center hubcap. When you put a magnesium
wheel back on, be sure the O-rings are correctly
installed. On the inboard side, of the wheel, work the
O-ring into the groove. When properly installed, this
O-ring fits snugly. The other O-ring goes around the
retaining legs of the center cap.
Used Replacement Wheels
CAUTION:
{
Putting a used wheel on your vehicle is
dangerous. You can't know how it's been used
or how far it's been driven. It could fail suddenly
and cause a crash. If you have to replace a
wheel, use a new GM original equipment wheel.
