Some 1990-1993 Eldorados, Sevilles and Allantes may experience a squawk noise from the front suspension during large suspension travel (i.e., going through a dip). This condition is most noticeable in cold temperatures and may occur for only the first few jounces after a cold soak. The condition is caused by the stabilizer shaft rotating within the stabilizer shaft insulator.
To repair this condition replace the stabilizer shaft insulator with the new service part which has a Teflon insert. Refer to the Service Parts Identification Label for suspension option code (FE1, FE2, or FE3). The insulators should be installed per Service Information Manual procedures with the slit toward the rear of the car.

In 1992, early built cars did not have a nut welded to the frame for the stabilizer bracket. On these cars it may be necessary to use a back up nut, P/N 11503643, on the underside of the frame when tightening the stabilizer bracket to prevent the bolt from stripping the threads in the frame.

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.
