CONDITION:

--------- Some owners of 1985-91 Eighty Eight, Ninety Eight, Toronado And 1990-91 Silhouette models may comment about a squeak or squawk noise coming from the front of the vehicle in or near the front wheels. This condition may be caused by insufficient grease on the lip seal of the hub assembly.

Note: For 1992 model vehicles, this condition has been eliminated with the introduction of a new Hub Assembly design, which requires no lubrication.

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.
