After having my car at the dealer for 3 days they finally fixed the cricket/creaking noise. They hooked a bunch of mics and stuff to it. They said in the process they heard other noises and fixed all those. They basically retorqued all the rear suspension bolts. They said they fixed the cricket noise by tightening the rear axle nuts. Hope this helps some of you.

 

I've got the same problem. Thanks for this post. It will help my dealer fix it the first time.

CLS,
Which dealership did you go to in GA ? I need to get this fixed myself.
