THIS BULLETIN HAS BEEN REVISED TO CHANGE THE LABOR OPERATION NUMBER. THIS BULLETIN CANCELS AND REPLACES BULLETIN 91-3-20 ISSUED 10/91. PLEASE DISCARD BULLETIN 91-3-20.

CONDITION:

Some 1985-91 Sunbird and Grand Am models might exhibit a condition of a "Squawk" OR "Clunk" noise from the front suspension or engine compartment area when driving over small bumps or entering parking lots (i.e. washboard road surfaces, railroad tracks).

CAUSE:

The condition may be caused by the rubber bushing material bleeding through the teflon/polyester sock and coming into contact with the stabilizer bar.

CORRECTION:

If this condition is encountered, replace both stabilizer bar bushings with newer designed bushings. The part numbers for the new bushings are listed below:
