Have any of you had this problem?
When I'm driving down the interstate between 78 and 83. (which I normally cruise at 79, yes I know the speed limit is 70) I get a fluttering noise coming out the right rear (when I'm driving). The dealer said it was an exhaust moan and was not repairable. It would be something I have to live with. I just found this site this morning and wish I knew it was here along time ago. Any Ideas what this could be? It doesn't occur at any other speeds. So that eliminates most things. and the Diff checked out ok as well.
