# 07147A - (01/03/2008)

Models:
2007 GMC Acadia
2007 Saturn Outlook

All-Wheel Drive

THE PARTS INFORMATION 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.

Purpose

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.

Vehicles Involved





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 shown. should be checked for vehicle eligibility in the appropriate system.
