Just a quickie update...
Pulled both belts off and ran it with no change in sound...
Looked up a few youtube vids of flexplate sound and it's starting to make me feel more confident in the noise that is coming from below...
I'm now thinking I should drop the tranny and do it from there...This way I can replace my CV's as I think one of those is toast...
Thanks again all, I'll post more when I figure it out.
