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
