SUBJECT:
ROOF LUGGAGE RACK WIND NOISE (REDESIGNED CROSS RAILS)
MODELS:
1992 C/K SUBURBANS AND UTILITIES
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. The wind noise may be emanating from the roof luggage rack. The roof rack cross rails have been redesigned for the 1993 C/K
Suburbans and C/K utilities. This bulletin provides the installation procedure for the redesigned cross rails and sliders on the roof luggage racks.
The new design for the cross rails is symmetrical and eliminates the need for positioning the rails in a particular direction.
