CREAK NOISE ON ACCELERATION OR DECELERATION

MODELS/YEARS: 1987 NINETY-EIGHT MODELS WITH STANDARD SUSPENSION

Some 1987 Ninety-Eight models may develop a noise at the rear frame to body mounting area. The noise can originate on either side of the vehicle and is caused by the position No. 3 frame to body insulator. The noise sounds like a creak in the door area and occurs on start and stop movement of the vehicle.

To correct the condition, both No. 3 insulator assemblies must be replaced (even if the noise only came from one side) as follows:

1. Remove the No. 3 position insulator assembly and discard. Figure 1. Support the frame as necessary during this operation since the position 2 mount must also be loosened.

2. Install the revised No. 3 mount as illustrated in Figure 2.

3. Torque all bolts to 103 N.m (76 lbs. ft.).

4. Repeat steps 1 through 3 for position No. 3 mount on the other side of 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.
