do any of you people actually believe the grease your slinging in here..
word.
grease is a hydrocarbon thats solid at room temprature, but does liquify when heated, so thats what keeps the bearing lubed..not the giant blobs of grease.
saying that, as the grease used up by the bearing, new grease has to be there to replace it,
and it's almost impossible to over grease a axle
Believe what you like but after 15 years building and repairing trailers I've got a pretty good idea what works and what doesn't.
If the bearings in a trailer hub get warm enough to liquify the grease something is wrong, the grease will soften but it never liquifies. I have seen them with a hub full of old grease and dry bearings, that grease will never force it's way into the bearings it just lays in there. Bearings in an axle hub aren't going a zillion miles an hour, not really a good comparison.

Another important factor is to not overtighten the hub.
Very true, more so than the amount of grease you have stuffed in there.
