DIFFICULTY INSTALLING LUGGAGE RACK

We have heard of some poor fitting roof racks causing installation difficulties on the 1984 6000.

The condition may be due to the cross rails being 6mm (1/4") too long. This requires the side rail supports to be forced inboard on installation and prevents fore and aft adjustment of the cross rails.

This condition has been corrected by the supplier. However, those cars already produced may require the following revisions of the cross rails to permit free movement:

1. Remove 6mm (1/4") from one end of each cross rail.

2. Drill a new 6mm (1/4") hole 9mm (3/8") from the revised end to align with the hole in the slider.

3. Remove all sharp edges with a file and assemble the rack per the instructions in the package.

When installing the threaded plate in the slider, inspect the plate for burrs on the corners. Assemble the plate in the slider so the large burr will follow the groove in the side rail and not bite into the metal when tightened. DO NOT grind the burr off as the protective coating will be broken and the plate will rust.

There have also been instances of screws missing from the packages. The following is a list of the screws and nuts used in the roof luggage carrier package.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those 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 a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
