Okay... I left off after page ten, but will go back and read later. I'm at work now. Can't read all day.
I also have a noise at cold startup. It's not just one clank. It's usually a random series of noises. More like loud clicks. To me, it sounds like the starter gear is not retracting completely, and maybe dragging on the starter ring, on the flexplate. I figure that, given enough time and left alone, it will probably "self clearance", and get quieter or, worst case, the starter will fail.
(Seems like I've also heard this noise come from other Chrysler products. Many years ago, before Diamler, even.)
