Found this detail here, but it seems to make a conflicting statement...
If only the outside bearing gets any grease, how does the inner seal get blown out?
While you have your hubs and wheels off now is a good time to check your springs, axle, and other suspension pieces. If you boat mainly in freshwater, your springs will probably look O.K. If you boat in saltwater, be prepared to replace your springs every few years depending on how much you use your boat. There should be no scaly rust on the springs and the leaves of the springs should be sandwiched tightly together. The axle should not be bent (duh!) Or have an abnormal amount of rust. The one item that should not be overlooked on the axle is the place where the hub seal rides. This area should be completely smooth no rust pits or grooves. If the seal does not fit tightly around this part of the axle, you can expect nothing but problems. If you do find that you need to replace your axle, it would be worth your while to search for a type of axle that has a grease fitting on the end of the spindle itself. This eliminates the need for any other type of lubrication device like bearing buddies. In my opinion, this is the best type of axle you can buy. With bearing buddies, only the outside bearing gets any grease. Bearing Buddies are better than having nothing at all but caution must be used not to overgrease and blow out the rear seal. If you are slinging grease on the insides of your trailer wheels it is time to replace your hub seals and quite possibly your bearings and races also. With the accu-lube or posi-lube style axle the inside bearing gets the grease first and with each pump of the grease gun flushes the old grease and water (if any) out through the end of the hub at the tip of your grease gun. There are oil bath systems out there, but, in my opinion, are complicated, expensive, and replacement parts are hard to come by.
