Low frequency growling noise

1521 Views 3 Replies 3 Participants Last post by  jlkans
My 2008 CTS AWD has developed a low frequency growling drive line noise most noticeable from 20 to 45 mph. Has 40000 miles on it and this problem has developed within the last 1000 miles. Is there a service bulletin that addresses this problem ? Getting ready to take it to the dealer and would like any information available that will assist them in correcting this problem.
Thanks in advance
