FRT.SUSPENSION SQUAWKING NOISE 84-86 CIMARRON

MODELS AFFECTED: 1984 - 1986 CIMARRON

This bulletin supersedes Serviceman Bulletin T-85-13, Group 3C, which should be destroyed. Some 1984 and 1985 Cimarrons, and 1986 Cimarrons built with 2.8L engines prior to B.C. 509794 and with 2.0L engines prior to B.C. 510778 may exhibit a "squawking" noise when subjected to significant jounce/rebound suspension motions. This condition may be caused by the front stabilizer bar bushings. Vehicles experiencing this front suspension noise condition may be repaired by installing two new insulators; P/N 22532212 for vehicles equipped with the 2.0L L-4 engine and P/N 22532213 for vehicles equipped with 2.8L V-6 engines.

Replace insulators, one side at a time, using the following procedure:

1. Raise vehicle on frame contact hoist.

2. Remove front wheel.

3. Disconnect stabilizer link at control arm.

4. Remove stabilizer bar mounting clamp nuts at front suspension support assembly.

5. Remove bolts from center and rear of suspension support assembly (see Figure 1).

6. Lower suspension support assembly away from body by pivoting at front bolts. This will provide access to stabilizer clamp and insulator.

7. Remove stabilizer clamp and insulator.

8. Install new insulator on the stabilizer bar. Reposition clamp on insulator.

9. Reposition front suspension support assembly. Install all bolts hand-tight.

10. Tighten bolts to proper torque specification in the following sequence:

A. Center Bolts - tighten to 95 N.m (70 ft. lbs.).

B. Rear Bolts - tighten to 90 N.m (66 ft. lbs.).

C. Stabilizer Bar Mounting Clamp bolts - tighten to 22 N.m (16 ft. lbs.).

11. Reinstall stabilizer link and tighten to 22 N.m (16 ft. lbs.).

12. Replace front wheel.

13. Repeat this procedure for opposite side.

For warranty purposes, use labor Operation E2180 at .7 hour.

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.
