Low frequency growling noise

1522 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

I've noticed mine is doing this too lately. I looked under the hood and while I'm not sure what the belt is, the belt which is front most on the engine is shaking a bit harder than it had been. This might be the cause of your noise.
