It is not really how much you pack in the bearing because you can only get so much in there. It is everywhere else that you want to be particular about. Don't fill the cap all the way up. I usually just put some in there up to the "edge" where the inside diameter changes. I usually just coat the spindle and inside of the bearings good. I just brought this up because there is a "capacity" rating per wheel. Don't have the info here in front of me though. Personally, I have never weighed it when I have redone one.
