LIMITED SLIP DIFFERENTIAL CASE SERVICE

1986 BONNEVILLE AND 1986-87 GRAND PRIX AND FIREBIRD MODELS

The 1986 Bonneville and 1986-87 Grand Prix and Firebird 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.
