CAMPAIGN: STEERING LINKAGE LOOSE TIE ROD/RELAY ROD NUTS

MODEL AND YEAR: 1987 CHEVROLET S10 TRUCKS ASSEMBLED AT MORAINE TRUCK ASSEMBLY

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 Branch 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 in certain 1987 Chevrolet S10 Trucks. The inner tie rod to relay rod nuts on the steering linkage may have been improperly torqued and not crimped. A loss of one or both of these nuts could lead to the inner tie rod disengaging from the relay rod. resulting in a possible loss of steering control which could lead to a vehicle crash without prior warning.

To prevent this condition from occurring, it will be necessary to replace the steering linkage assembly.

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.
