This bulletin cancels and supersedes Dealer Technical Bulletin 92-T-100 which should be discarded.

CONDITION: On a smooth, flat road, the vehicle may exhibit a type of lead or pull condition. This would be directly following the completion of a turning maneuver. When the steering wheel is returned to a straight ahead position, the vehicle may tend to lead or pull in the last direction turned. This is known as "Memory Steer". This condition is always noted as being in the same direction as the last turning maneuver.

CAUSE: The upper strut mounting bearing may be sticking or binding which may cause a preload on the strut. This preload may cause the vehicle to move in the last direction turned, thus causing "Memory Steer".

CORRECTION: Replace both the upper strut mount assemblies with the following, (2 per vehicle, right and left): Parts are currently available from GMSPO.

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.
