Condition

Some customers may comment on a clicking noise emanating from the front wheels
location. This condition may be more predominant at low speeds (10-20 mph or

This may be caused by interaction between the wheel mounting face and the wheel
mounting surfaces on the brake rotor.

Correction

for this condition.
If you encounter a vehicle with the above concern,

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
