Magnesium Wheels
Incorrect wheel nuts or improperly llyhtened
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 whee!
nuts in the proper sequence and to the proper
torque specification.
Notice: If your vehicle has magnesium wheels,
I
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 has 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, work the
O-ring into the groove. When properly installed, this
O-ring fits snugly. The other O-ring goes around
the edge of the center cap.
Used Replacement Wheels
I
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.
