LIMITED SLIP DIFFERENTIAL CASE SERVICE

#### VEHICLES AFFECTED: 1986-87 "F" AND "G" SERIES ------------------

1986 and 1987 "F" and "G" models equipped with limited slip differentials (G80) use an Auburn designed one piece case assembly. When service is required, the case will be serviced as a complete assembly. The pinion shaft screw is still serviced separately. Refer to 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.
