CAMPAIGN: TIE ROD CLAMP FASTENER INFORMATION

MODELS: 1984 C 35 PONTIAC BUILT

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 owner 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 a service date 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 owner is being instructed to contact the nearest GMC Zone Office if their dealer does not remedy the condition within five days of the mutually agreed upon service date. If the oondition is not remedied within a reasonable time, they are instructed 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 in some 1984 C 35 GMC vehicles. The toe-in may not have been set, nor the tie rod clamp fasteners torqued. Should this condition exisit, one of the tie rods could separate. If this were to occur while the vehicle is in motion, it could result in a loss of steering control and a vehicle crash could occur without prior warning.

To prevent the possibiliy of this condition occurring, dealers are to determine if the tie rod clamp fasteners have been torqued. If the clamps are loose, it will be necessary to set the toe-in and torque the tie rod clamp fasteners.

VEHICLES INVOLVED

Involved are certain 1984 C 35 model trucks identified within the following vehicle breakpoints.

Plant From Through ----- ---- ------- Pontiac EV504713 EV506027

OWNER NOTIFICATION

Owners will be notified of this campaign on their vehicles by GMC Truck (see copy of Owner Letter included with this bulletin). A listing of owner names and addresses has been furnished to the involved dealers to enable dealers to follow up with owners involved in this campaign. This listing 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 this campaign.

INSPECTION PROCEDURE

Determine if a square green inspection sticker is present on the front bumper, as shown in Figure No. 1. If this sticker is present, no further action is required.

If the sticker is not present on the bumper, the tie rod clamp fasteners shown in Figure No. 2 must be inspected. If the toe in was not set, these fasteners will be finger-tight. Using a torque wrench, measure the amount of effort required to move the fastener in a clockwise direction (tighter). If the fasteners have been torqued to 16-22 N m (12-16 lb. ft.) on the C35 (Figure No. 2) no further action is required.

If the tie rod clamp fasteners have not been torqued to the values specified above, the toe-in must be set and the fasteners tightened, according to the service procedure in this bulletin.

SERVICE PROCEDURE

Adjust vehicle toe-in as specified in Section 3A, "Front Alignment" in the 1984 Light Duty Service Manual, X-8432. Make sure the tie rod clamp fasteners have been positioned correctly and follow the torquing procedure specified in Section 3B6, "Steering Linkage".

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.
