whichever way you go i'd recommend getting a suspension w/ an axe fitted w/ EZ-LUBE SPINDLES
they are available on axles from several manufacturers
they can be identified by their dust cap which typically has a rubber plug in the end

pop the rubber cap out and there is a grease zerk on the end of the spindle itself
using a grease gun you lube the bearings and keep the hub cavity full at all times
the grease goes in thru the center of the spindle and exits between the rear seal and the inside bearing
then it flows thru the inner bearing filling the hub and oozing out thru the outer bearing
this process keeps fresh grease in your bearings and the older grease comes out the dust cap where it can simply be wiped away

keeping the hub full of grease prevents water and dirt intrusion
lubing once /season and prior to any major event will keep you rolling w/ freshly greased bearings for years to come
i jack the tire off the ground and spin it
if i don't hear any growling i simpy grease the nipple until i get clean grease coming from around the spindle nut
while at it i remove my lug nuts n clean the threads on the bolts and in the nuts then spray my favorite rust preventitive on the threads and replace the nuts torquing them by hand with the lug wrench i carry in the truck so i am sure i can get them back off if needed
i use that blue/green boat trailer wheel bearing grease in all my trailers and farm implements
the last time i found myself on the side of the road w/ bearing issues was in the mid 1970's just before i started this regime
i also do this with each new trailer/axle i get replacing unknown grease with stuff i know i can count on
i just start pumping the blue/green stuff in and the original stuff comes out
in this case the stock grease was red
