My take on this is that when you buy new bearings, they are not covered with grease. You would'nt rebuild an engine or transmission without cleaning it before assembly (I never have anyways). Parts have to be clean. Just wiping the grease off will not remove the small metal particles that all moving parts aquire after a while. If these particles are not removed, it's a waste of time repacking them in my opinion. It would kind of be like changing the oil and not the filter.
