SOME 1984-1992 BROUGHAMS MAY EXHIBIT A CONDITION WHERE THE TIRE RUBS THE FRAME OR STABILIZER SHAFT ON FULL TURNS SUCH AS IN PARKING LOT MANEUVERS. THE RUBBING CONDITION MAY BE HEARD AND/OR FELT. AS THE TIRE RUBS THE FRAME OR STABILIZER SHAFT, IT WILL LEAVE A SHINY SPOT ON THE AREA OF CONTACT. THE SIDEWALL OF THE TIRE MAY ALSO SHOW A SLIGHT SCUFFING, HOWEVER, THE INTEGRITY OF THE TIRE IS NOT AFFECTED.

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.
