When I had a clunking noise that was heard backing out of the garage it turned out to be the transmission output bearing...

From bad to worse.. my sound is more like clunking and less like sandpaper.  I suppose I need to have a gander at the shop manual and check it out before something bad happens.

The critical thing with general "bad" sounds coming from the movement of the rear wheel is trying to isolate the source, as you've got bearings of various types in the wheel, final drive, driveshaft u-joint and transmission output shaft all turning with the gearbox in neutral.  Not to mention the spring cush drive in the driveshaft assembly - which can (though quite rarely) fail and cause clunking/knocking noises.

I had the side of a brake shoe rub against the wheel.

What you describe doesn't sound like a bearing unless it's really really dry.
