I found that the absolute best way to pack bearings is to use a sandwich baggie, its the most clean way and makes sure you have grease in the roller areas. Furthermore you can use that baggie to squeeze the remaining into the hub as mentioned in the repair manual.

Im looking for my favorite bearing grease but apparently penzzoil have stopped selling it.
