Customer Satisfaction -- Loose Rear Differential Bolt - Noise
# 07271 - (10/01/2007)
Models:
2008 Cadillac CTS
THIS PROGRAM IS IN EFFECT UNTIL OCTOBER 31, 2008.
Condition
On certain 2008 model year Cadillac CTS vehicles, one or more ring gear bolts in the rear differential may not have been tightened to specification. If a
bolt loosens and backs out, the bolt would contact the internal surfaces of the differential housing. The metal-to-metal contact would produce a metallic
noise. Continued operation could result in damage to the differential housing which would be accompanied by a loud noise.
Correction
Dealers are to replace the rear differential.
Vehicles Involved
Involved are certain 2008 model year Cadillac CTS vehicles built within the VIN breakpoints shown.
IMPORTANT:
Dealers are to confirm vehicle eligibility prior to beginning repairs by using the GM Vehicle Inquiry System (GMVIS). Not all vehicles within the
above breakpoints may be involved.
For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address
information has been prepared and will be provided through the applicable system listed below. Dealers will not have a report available if they have no
involved vehicles currently assigned.

The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration
data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you
are urged to limit the use of this report to the follow-up necessary to complete this program.
Parts Information
NOTICE:
The rear differential is shipped without fluid. To avoid part damage, add the required amount of fluid to the rear differential. Refer to Lubrication
