Service Update for Inventory and Customer Vehicles-Propeller Shaft Bolts-Expires with Base Warranty

THE PARTS NIFORMATION AND SERVICE PROCEDURE SECTIONS OF THIS BULLETIN HAVE BEEN REVISED TO INCLUDE ONE, TWO, OR THREE WASHERS, IF NECESSARY. PLEASE DISCARD ALL COPIES OF BULLETIN 07147, ISSUED JUNE 2007.

THIS SERVICE UPDATE INCLUDES VEHICLES IN DEALER/RETAILER INVENTORY AND CUSTOMER VEHICLES THAT RETURN FOR ANY TYPE OF SERVICE, AND WILL EXPIRE AT THE END OF THE INVOLVED VEHICLE'S NEW VEHICLE LIMITED WARRANTY PERIOD.

This bulletin provides a service procedure to install six new propeller shaft-to-transfer case bolts in certain 2007 AWD GMC Acadia and Saturn Outlook vehicles. The new bolts improve the durability of the joint. Some bolts have become loose on vehicles with the earlier production bolts. Separations of the propeller shaft, which would require all six bolts to loosen and back out, have not occurred and are not likely. Separation would cause only noise and vibration; driving through the front wheels would be unaffected

This service procedure should be completed as soon as possible on involved vehicles currently in dealer/retailer inventory and customer vehicles that return to the dealer/retailer for any type of service during the New Vehicle Limited Warranty coverage period.

A list of involved vehicles currently in dealer/retailer inventory is available on the "Service Update Bulletin Information" link under the "Service" tab in DealerWorld (GM and Saturn US) or attached to the Dealer Communication (Canada) used to release this bulletin. Customer vehicles that return for service, for any reason, and are still covered under the vehicle's base warranty, and are within the VIN breakpoints provided below, should be checked for vehicle eligibility in the appropriate system listed below.

Important: Dealers/retailers are to confirm vehicle eligibility prior to beginning repairs by using the system(s) below. Not all vehicles within the above breakpoints may be involved.

Parts required to complete this service update are to be obtained from General Motors Service and Parts Operations (GMSPO). Please refer to your "involved vehicles listing" before ordering parts. Normal orders should be placed on a DRO = Daily Replenishment Order. In an emergency situation, parts should be ordered on a CSO = Customer Special Order.
