CAMPAIGN: INCORRECT FRONT AND REAR SPRINGS (POLICE)

Model and Year: 1985 FULL SIZE CHEVROLET MODELS EQUIPPED WITH SEO 9C1 (POLICE PACKAGE) AND (SPECIAL HANDLING SUSPENSION) SEO 7B3 AND ASSEMBLED AT WILMINGTON ONLY

TO: ALL CHEVROLET DEALERS

General Motors has determined that some 1985 Full Size Chevrolet models equipped with SEO 9Cl (Police Package) and (Special Handling Suspension) SEO 7B3 may have been assembled with standard front and rear springs rather than the heavy duty springs that were ordered. As a result, accelerated suspension deterioration can occur.

To correct this condition the front and rear springs will be inspected and when required, replaced on all involved vehicles.

VEHICLES INVOLVED

Involved are certain 1985 Full Size Chevrolet models equipped with SEO 9CI (Police Package) and (Special Handling Suspension) SEO 7B3 within the following parameters:

Involved vehicles have been identified by Vehicle Identification Number Computer Listings. Computer listings contain the complete Vehicle Identification Number, owner name and address data, and are furnished to the involved dealers with the campaign bulletin. Owner name and address data furnished will enable dealers to follow-up with owners involved in this campaign.

These listings may contain owner names and addresses obtained from State Motor Vehicle Registration Records. The use of such motor vehicle regis- tration data for any other purpose is a violation of law in several states. Accordingly, you are urged to limit the use of this listing to the follow-up necessary to complete this campaign. Any dealer not receiving a computer listing with the campaign bulletin was not shipped any involved vehicles.

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.
