After reading elsewhere in the forums about another member (Joe Black) who cured his "clunk" noise by replacing the trans. mount, I couldn't NOT take it all apart to see (that wasn't it)...figured as long as I had it out, WTH, might as well pin that sucker solid & never give it another thought...
That lead me to the conclusion that I probably have a broken motor mount, I'll be getting to that "whenever"...maybe even before Moab...
I also have a suspicion that the mounts for the lower links have become egg shaped from violent acceleration & braking...another thing I'm gonna have to look into one of these days.
