ADMINISTRATIVE MESSAGE 01-330 CREATED ON 11/16/90

TO: ALL CHEVROLET/GEO DEALERS

SUBJECT: DEALER SERVICE BULLETIN 90-33O-3E - "SPARE TIRE CARRIER RATTLE"

THE FOLLOWING INFORMATION SHOULD BE COMMUNICATED TO ALL TECHNICIANS INVOLVED IN REPAIRING SPARE TIRE CARRIER RATTLE ON 1986-1991 S/T BLAZERS.

A COPY OF THIS MESSAGE SHOULD ALSO BE ATTACHED TO DEALER SERVICE BULLETIN 90-33O-3E.

1. THE LATCH SYSTEM USED ON THE 1986-91 S/T SPARE TIRE CARRIER CONSISTS OF A DOUBLE LATCH MECHANISM AND FUNCTIONS SIMILAR TO THE DOUBLE LATCH EMPLOYED ON HOOD ASSEMBLIES. THE INITIAL LATCH PROVIDES FOR A BACKUP, SHOULD THE MAIN LATCH BECOME DISENGAGED. HOWEVER, THE VEHICLE IS INTENDED TO BE OPERATED WITH THE SPARE TIRE CARRIER LOCKED IN PLACE BY THE MAIN LATCH.

CONCERNS OF SPARE TIRE CARRIER RATTLE MAY BE CAUSED DUE TO THE CARRIER ASSEMBLY NOT BEING COMPLETELY CLOSED, BUT RATHER ENGAGED BY THE INITIAL (BACKUP) LATCH ONLY.

PRIOR TO ATTEMPTING ANY REPAIRS, AND BEFORE PROCEEDING WITH BULLETIN 90-33O-3E, TECHNICIANS SHOULD OPEN AND THEN FIRMLY CLOSE THE SPARE TIRE CARRIER, VERIFYING THAT THE MAIN LATCH IS FULLY ENGAGED. IF NECESSARY, ROAD TEST THE VEHICLE TO CONFIRM THAT A RATTLE CONDITION STILL EXISTS BEFORE PROCEEDING WITH THE BULLETIN.


2. PRIOR TO ADJUSTING THE RUBBER BUMPER, ASSURE THAT THE NEW ARM IS FULLY ENGAGED IN THE MAIN LATCH MECHANISM. FAILURE TO HAVE THE CARRIER ARM LOCKED IN THE MAIN LATCH WILL RESULT IN AN IMPROPER ADJUSTMENT TO THE BUMPER.

3. THERE IS A TYPOGRAPHICAL ERROR AT THE BOTTOM OF PAGE 4 IN THE PARAGRAPH DIRECTLY FOLLOWING THE WORD IMPORTANT! THE PARAGRAPH SHOULD READ:

"THE RUBBER BUMPER WILL CAUSE THE SPARE TIRE CARRIER TO CLOSE HARD FOR A COUPLE OF WEEKS. EVENTUALLY THE RUBBER WILL TAKE A PERMANENT SET AND THE CARRIER WILL CLOSE WITH REASONABLE EFFORT."
