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.
Yeah I totally understand your side. I bough the car with 44k miles the axle breaking due to the shops fault was around 45-46.5k miles, i now have 49k and the sound came around 48k. Before the wheel bearing and axle issues i heard no noise at all. Its weird that it came so late. Ill get a diff change in the coming weeks to see if it fixes it and hope it does. Sound is only for a split second and then cant duplicate it until a fee tries lol
