I can only speak from my personal experience. The diff rub sound is supposedly completely normal. Mine does not always do it at the place or two I have had it happen, but does happen more times than not. Maybe we both have bad diffs? I don't worry about mine since the sound is "normal" and has not changed, other than doing it less after my first 1000 miles, in over 10K since the fluid was changed. Maybe someone else will chime in with a better explanation.
