The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
The rear axle carrier assembly on the 2008 Cadillac CTS includes a mass dampener assembly. If the rear axle carrier assembly is replaced for any reason, the dampener and bracket needs to be transferred to the replacement unit.
When replacing the rear axle assembly for any reason, remove the mass dampener and bracket from the original unit, and install it on the new axle. For additional information, see SI Document #2030230.
Important Note: If the dampener assembly is not installed on the new axle, a driveline noise or vibration will result at approximately 55 to 65 mph (90 to 105 kph).
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
