SUBJECT: FRONT SEAT BACK RATTLE AT PIVOT BOLT - INSTALL NEW BOLT AND BUSHING

MODELS AFFECTED: 1986-89 SKYHAWK 1986-87 SOMERSET 1988-90 SKYLARK


A condition of seat back rattle, popping or seat chucking on turns may be caused by the front seat back inner pivot arm moving on the pivot bolt.

To correct the condition a new pivot bolt and bushing have been released that have a shorter shoulder length to prevent side movement of the seat back pivot arm on the pivot bolt.

The new pivot bolt and bushing should be used together and are listed as follows:

^ Bolt 22543387
^ Bushing 22543386

Replace only the affected bolt and bushing.
