That is the question. Do you pack the channel full of grease, or just apply liberly to both bearings? How much is too much or not enough?

Pack the bearings real good ,any grease you put in the hub is wasted. though i have seen people do that all the time not sure where they ever got the idea to do that.
One thing i have strated doing is using water proof grease it's what they use for boat trailers and it's much better stuff.

Gary is right about the waterproof grease. If you do get a little too much grease in there, it won't hurt anything, but if you don't get enough it will. Just make sure the bearings are packed really well.

Just for your info, I work on tractor trailers as well as cars, if you pack the hub full with grease, it is more likely to catch fire than if just a generous coat on the bearings. I have seen trucks with greased bearings, and with oil lubed bearings. Obviously they have more braking power and heat to disipate, so I usually just use normal wheel bearing grease on my cars, but I constantly take my car apart for fun and re grease them for pure enjoyment once in a while LOL.

they sell bearing packers but you can do a good job by filling both palms with grease and push them together with bearing in middle. do this a few times working grease around. doubt you can get too much in but not necesssaryk to fill hub.

Yes grease should be placed into the cavity of the hub,You don't FILL the cavity, but a small amout behind each bearing and a thin layer in the hub is fine, it serves a purpose, it is not just wasted grease.
I would also use a quality disc brake wheel bearing will withstand higher temps and will not run out of the bearings when hot. Marine wheel bearing grease is not up to this task.Most boat trailers don't even have brakes and the bearings will not see the temps seen automobiles.Yes it resists water intrusion better, but will you be submerging your axles? The reason boat trailer grease need to resist water is because when launching the boat after a nice highway tow you back the trailer with its hot bearings into the water. The introduction of the cool water to the hot surfaces results in the water being sucked into the hub past the seals washing the grease out.
Do a google seach of "repacking wheel bearings"
you will find many if not the same proceedures on all the sites
