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).

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