2004 Cadillac Cts. The car has made a loud noise in the differential since purchased. The differential was replaced however, the noise and jerking of rear wheels continues. I have returned to the dealer several times only to be told there is nothing wrong with the vehicle. I have replaced the tires three times because the dealer said they were the source of the noise and jerking, but the condition still exists. I have checked the internet and information listed reveals the Cadillac Cts has a major defect in the drive train however gm has not acknowledged.
