Wheel Bearing Packer

I've used one of those packers shown above a couple of times, but I really prefer packing them by hand. I put a pretty good dollop of grease on my left palm, and use kind of a scraping motion with the big end of the bearing cone against the edge of the ball of grease. As the grease is forced thru the rollers, you can see it coming thru the small end of the cone''s cage, then you just rotate the cone in your right hand, to an adjacent ungreased area and repeat until the bearing cone is completely greased. Once you've done it a couple times, you get pretty fast at it, and you are 100% assured the cone is 100% greased.
