It could be a U-Joint, but for some reason I have this thing popping in my mind that it has to do with the rear end maybe because I remember reading a TSB for an issue like this but I just can't remember the provisions or the TSB for that matter. If It pops back in my mind I will tell you what Chrysler said it was.I have a 2002 1500 4x4 Ram with 5.9 (103K miles). I have noticed that lately when I pull out I get a little vibation/shutter that feels like it's coming for the rearend area. I also have some noise at times when moving slow through a parking lot. Sometimes a clicking sound and other times like a dry rubbing sound. I'm thinking I have a U-joint going bad. Thought?
