INFO. ON FRONT END ALIGNMENT PRIOR TO 500 MILES. Pontiac Sunbird 1993

THIS BULLETIN CANCELS AND REPLACES BULLETIN 980110.

PONTIAC DATA INDICATES THAT A NUMBER OF FRONT END ALIGNMENTS ARE BEING PERFORMED DURING THE PRE-DELIVERY INSPECTION OF A VEHICLE OR SHORTLY THEREAFTER. THERE IS SUFFICIENT ENGINEERING DATA INDICATING THAT THIS PRACTICE COULD CREATE AN ALIGNMENT PROBLEM FOR OUR OWNERS LATER IN THE WARRANTY PERIOD OF THE VEHICLE. ENGINEERING TESTS SHOW THAT GEOMETRY CHANGES CAUSED BY TRANSPORTATION FROM THE ASSEMBLY PLANT OR FROM A "GREEN" SUSPENSION WILL USUALLY RECOVER WITHIN APPROXIMATELY 500 MILES.

IN VIEW OF THIS INFORMATION AND WITH RECEIPT OF THIS BULLETIN, YOU ARE ASKED TO REFRAIN FROM PERFORMING FRONT SUSPENSION ALIGNMENTS ON ANY VEHICLE BEFORE IT REACHES 500 MILES. IN THE UNLIKELY EVENT THAT YOU WOULD NEED TO PERFORM AN ALIGNMENT PRIOR TO 500 MILES PRIOR ZONE AUTHORIZATION IS REQUIRED AND THE ATTACHED SHEET SHOULD BE COMPLETED AND MAILED TO THE ADDRESS INDICATED. A COPY OF THE COMPLETED SHEET SHOULD ALSO BE ATTACHED TO THE SCRAPPING COPY OF THE WARRANTY REPAIR ORDER FOR REVIEW. THIS WILL ASSIST ZONE PERSONNEL, AUDIT STAFF AND TECHNICAL SERVICES IN UNDERSTANDING THE CONDITIONS NECESSITATING FRONT SUSPENSION ALIGNMENT EARLY IN THE LIFE OF THE VEHICLE.

PROPERLY TRAINED TECHNICIANS HAVE THE EQUIPMENT, TOOLS, SAFETY INSTRUCTIONS AND KNOW-HOW TO DO A JOB PROPERLY AND SAFELY. IF A CONDITION IS DESCRIBED, DO NOT ASSUME THAT THE BULLETIN APPLIES TO YOUR VEHICLE, OR THAT YOUR VEHICLE WILL HAVE THAT CONDITION. SEE A GENERAL MOTORS DEALER SERVICING YOUR BRAND OF GENERAL MOTORS VEHICLE FOR INFORMATION ON WHETHER YOUR VEHICLE MAY BENEFIT FROM THE INFORMATION.
