If you're going to pull, clean, inspect, repack, and reassemble the bearings each year, why not replace the grease seals as well? Seems kind of silly to save the $2.45 (which was the grease seal price last time I looked) if you've got access to the area anyway.

If it takes a breaker bar and corresponding socket to get the hub nut off of a roller bearing setup, it's way too tight. Should be just snug, which you can usually do by hand. Granted, a hub that's been used and neglected for a couple of years my have baked on grease and sludge and such, but usually just a large crescent wrench will get it started, and then you can spin it off with finger power. Note that this applies to roller bearings; I don't know a thing about the sealed bearings you were discussing.
