I'm glad it was resurrected, actually, because I have a question relating to this. I don't get a clunk shifting from Park or between Drive and Reverse, but I do have a drive train vibration when coasting. Sometimes it's pronounced, sometimes you can barely tell.
Anyway, it's been there for a few years and I replaced the front and rear u-joints when I first started noticing it, but that didn't change anything. CV joints wouldn't cause that, would they?
