Pack the Wheel Bearings Failure

I've done it both ways ,packer and by hand. By hand is a method that needs to be learned, you have to keep "working it" untill the grease pushed up into the race between the rollers. You need someone to show you rather than 'watch" if you know what I mean. basically grease on the outside isnt going to work, it needs to be up,in,and through the bearing. the packer is quick and easy and you can see the grease working through the bearing you know its properly packed.
