(REPLACE STABILIZER BUSHINGS WITH NEWER DESIGNED BUSHINGS)

MODELS AFFECTED: 1985-89 SKYHAWK 1985-91 SKYLARK AND SOMERSET


CONDITION:

Some 1985-91 Skylark/Somerset and 1985-89 Skyhawks 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.

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