10 3/16" balls is a very common count per front side. Usually there's a gap between the balls that almost but not quite allow for an 11th ball, but don't do that.


Cones and cups can have pitting/rough surfaces in one spot on the ball track which results in varing feel/sound spin. Dust caps (or seals) can be rubbing, thin sheet metal can make noises sound bigger then they are. Of course how the bearing adjustment is set also contributes. It's noy uncommon on old/worn hubs to need to set the bearing with a slight slop, to accommodate uneven wear and not have any grabby or rough spin. Andy
