I have the '21 3.0 diesel AT4. About 17,000 miles. Everything was awesome (had a few crank no starts but not many) until a week or so ago. I had been up in Maine driving on some nasty old logging roads and now when I go over anything like a speed bump or the divot at the end of my driveway I hear a klunk/knocking sound coming from rear suspension. Had the same issue with my old 2500 and the dealer never figured it out. But it is driving me crazy. Anyone else have similar issues? Almost sounds like a hnger for the muffler came loose or something. TIA
