CAMPAIGN:TIE ROD TOUCHES TIRE REPLACE TIRES AND WHEELS. Chevrolet Chevy P RV/Van/Commercial Chassis 1985

Model and Year: 1985 CHEVROLET P30 MODEL LIGHT DUTY TRUCKS EQUIPPED WITH I-BEAM FRONT AXLES (RPO FS3) AND 16" WHEELS AND TIRES

TO: ALL CHEVROLET DEALERS

The National Traffic and Motor Vehicle Safety Act, as amended, provides that each vehicle which is subject to a recall campaign of this type must be adequately repaired within a reasonable time after the owner has tendered it for repair. A failure to adequately repair within 60 days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.

If the condition is not adequately repaired within a reasonable time, the owners may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.

To avoid having to provide these burdensome solutions, every effort must be made to promptly schedule an appointment with each owner and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the letter which is being sent to owners, the owners are being instructed to contact the nearest Chevrolet Zone Office if their dealer does not remedy the condition within five days of the mutually agreed upon service date. If the condition is not remedied within a reasonable time, they are instructed on how to contact the National Highway Traffic Safety Administration.

DEFECT INVOLVED

General Motors has determined that a defect which relates to Motor Vehicle Safety exists on some 1985 Chevrolet P30 Light Duty Trucks equipped with an I-beam front axle and 16" wheels and tires.

During a combined cornering and braking maneuver, the tie rod end could contact the tire wall. This contact can cause grooving of the tire, which if it went unnoticed, could eventually result in a tire failure and a possible vehicle crash without prior warning.

To prevent the possibility of this occurring on the vehicles involved, the standard 16" wheels and tires (7.50-16 or LT215/85R16) will be replaced with 19.5" wheels and tires (8.00-19.5LT). This increases the clearance and eliminates contact between the tire and tie rod end.

VEHICLES INVOLVED

Involved are certain 1985 Chevrolet P30 model Light Duty Trucks equipped with I-beam front axles (RPO FS3) and 16" wheels and tires manufactured within the following VIN breakpoints:

PLANT FROM THROUGH ----- ---- ------- Detroit F3311186 F3346846

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 registration 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 has no involved vehicles currently assigned.

(Notification Used By Chevrolet Motor Division)

Dear Chevrolet Owner:

This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.

General Motors has determined that a defect which relates to Motor Vehicle Safety exists on some 1985 Chevrolet P30 Light Duty Trucks equipped with an I-beam front axle and 16" wheels and tires.

To prevent the possibility,of the condition occurring on your vehicle, please contact your Chevrolet dealer on or after the date shown below to arrange a service date. Your dealer will replace your 16" wheels and tires (7.50-16 or LT215/85R16) with 19-1/2" wheels and tires (8.00-19.5LT). This increases the clearance between the tie rod end and eliminates the possibility of grooving of the tire. In addition, your speedometer gear will be replaced to compensate for the new size wheels and tires. The service will be completed at no charge to you.

Instructions for making this correction have been sent to your Chevrolet dealer. It is estimated that parts will be available to your dealer on September 8, 1986. The labor time necessary to perform this correction is approximately 5-1/2 hours. Please allow additional time for the dealer to process your vehicle.

Your Chevrolet Dealer is best equipped to obtain parts and provide service to ensure your vehicle is corrected as promptly as possible. However, if you take your vehicle to your dealer on the agreed service date, and they do not remedy this condition on that date or within five days, we recommend you contact the nearest Chevrolet Zone Office, either in person or by telephone. The Zone Office will assist you and the dealer in getting your vehicle corrected. The locations and telephone numbers of the Zone offices are listed in your Owner's Manual.

After contacting your dealer and the Zone Office, if you are still not satisfied that we have done our best to remedy this condition without charge and within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 400 Seventh St., S.W., Washington, D.C. 20590 or call 800-424-9393 (Washington, D.C. residents use 426-0123).

The enclosed owner reply card identifies your vehicle. Presentation of this card to your dealer will assist them in making the necessary correction to your vehicle in the shortest possible time. If you have sold or traded your vehicle, please let us know by completing the postage paid owner reply card and returning it to us.

We are sorry to cause you this inconvenience; however, we have taken this action in the interest of your safety and continued satisfaction with our products.

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.
