Mine has it, my buddy's 3.7 Liberty has it....its just something that they do. When i put my cold air intake on it seemed to help a little but not much.

Mine does it too. I got the typical dealer answer, "its normal for this trucks".

Although, there is a tsb for excessive vibration on idle for rams with 5.7. It would be something to question the dealer about since it looks like the exhaust looks the same from the cats to the inlet to the muffler.

Spiff, does your make that "clang clang" noise in the morning or when the engine is cool? It sounds like its coming from the transmission on mine, but then it goes away after warm up.

YES it does, I didnt want to mention it, cause I thought maybe It was from driving it to hard, Im getting it checked out by a real shop next week, I will tell you what they say, It almost sounds like a lifter knock, but i dont hear it out the muffler and it goes away to quick
