Owners of some 1992 C/K Suburban and C/K utility models equipped with roof luggage racks may comment on unacceptable wind noise coming from the roof of the 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.
