General Motors of Canada has determined that certain 1990 S/T series 100 trucks may have improperly installed steering wheels. The nut attaching the steering wheel may have been insufficiently tightened and a nut retainer may be missing. This could allow the steering wheel to disengage from the steering column. Should this occur while the vehicle is in motion a vehicle crash could occur without prior warning.
To correct this condition the steering wheel nut and retainer will be reinstalled and the nut retorqued on all 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.
