What Vaughn suggests will work, but this is a case where everyone will have their own opinion.
I first coat the spindle, where the bearings do not ride, with grease in a layer about 1/16" thick. Then I coat the inside of the hub between the races with grease in a layer about 1/8" thick. I build up a berm of grease against each bearing race so when I slide the fully packed caged rollers into place, they contact this berm. These berms act as a reservoir for the caged rollers to assure that there is enough in place as the grease naturally migrates away from the rollers due to heating and cooling and centrifugal force.
This all insures that everything inside is coated, but still leaves a lot of room for required air space and expansion and contraction. The air space is what can get you in trouble. You do not want any of this air space to contact bear metal as it will attract moisture and the coating will help keep that moisture from contacting the bare spindle and the bare insides of the hub.
After installing the hub and outer bearing in place, I also add a berm of grease against the outer surface of the outer caged roller before threading on the adjuster nut.
