CAMPAIGN: STERRING SHAFT TO STEERING GEAR. GMC Truck Yukon

NOTE: GM OF CANADA CAMPAIGN 97048 IS LOCATED BELOW THE U.S. VERSION

SUBJECT: 97048 - STEERING SHAFT TO STEERING GEAR PINCH BOLT

MODELS: 1998 CHEVROLET AND GMC C/K EXTENDED CAB PICKUPS AND 4-DR. UTILITIES BUILT AT ARLINGTON ASSEMBLY PLANT (VIN CODE "R")

ON AUGUST 15, 1997, ALL VEHICLES INVOLVED IN THIS CAMPAIGN WERE PLACED ON STOP DELIVERY, AND DELIVERED VEHICLES WERE TO BE TOWED INTO THE DEALERSHIP. AFTER THE CAMPAIGN SERVICE PROCEDURE IS COMPLETED, THE VEHICLES MAY BE DELIVERED TO CUSTOMERS.

The Highway 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 customer has tendered it for repair. A failure to repair within sixty (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 customer 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 remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible. As you will see in reading the attached copy of the divisional letter that is being sent to customers, the customers are being instructed to contact the appropriate Customer Assistance Center if their dealer does not remedy the condition within five (5) 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 decided that a defect which relates to motor vehicle sa fety exists in certain 1998 C/K Extended-Cab Pickups and 4-Door Utility trucks built at the Arlington Assembly Plant. These vehicles may have been shipped with the lower steering shaft to steering gear pinch bolt "finger loose" or missing. A "finger loose" bolt could continue to loosen and fall out. With the bolt missing, the steering shaft yoke could wear and jump splines on the steering gear shaft causing an off center steering wheel. However, relative movement between the chassis and cab could cause the steering shaft to separate from the steering gear resulting in a loss of steering control and possible crash without prior warning.

To prevent the possibility of this condition occurring, dealers are to inspect for the presence of a pinch bolt and check to be sure it is torqued to the proper specification.

VEHICLES INVOLVED

Involved are certain 1998 Chevrolet and GMC C/K Extended Cab Pickups and 4-Dr. Utilities built at Arlington Assembly Plant (VIN Code "R") and built within the following VIN breakpoints:

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.
