#### VEHICLES AFFECTED: 1985 Deville And Fleetwood With PD8 Option ------------------------------------------

1985 Devilles and Fleetwoods Equipped with aluminum wheels (Option PD8) may not properly retain the centre hubcaps. If this condition is encountered, inspect the wheel to insure that a hubcap retention groove is present on the inside flat area of the wheel flange (See Figure 1).

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.
