Buick Service Bulletin 87-3-6 was published to provide a simple, convenient chart of all 1987 model passenger car wheel alignment specifications. It was not meant to imply that resetting was necessary at the dealership. In fact, with today's state-of-the-art factory alignment equipment and procedures, there should be even less need for resetting.
As in the past, alignment should be checked only when a specific customer condition relating to alignment is encountered. Such alignment checking/resetting should not be done until the customer has accumulated at least 500 miles so that suspension geometry has a chance to settle.
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.
