You will need to press the grease into the bearing, there is a tool but it’s easy to pack it by hand. I use latex gloves, put a glob of grease in the palm of your hand, push the bearing into your palm, get another glob of grease with your fingers and rotate the bearing through your palm pushing the grease between the rollers and the cage, saturating the bearing is extremely important.
After pressing in the races, fill the inner section of the hub, between the races with some grease, I use a moly lube called BR2, but most axle grease will work fine.
Thanks! I think I get what to do. One questions/clarification: Why am I filling in between the hubs? There's nothing there, is there? Nothing rolls on the axle. Just curious?
