ok a question now, the hubs came with a note "Dont grease" on the package so we just installed them as they were, but one of the "clutch plates", the one that goes on the driveshaft and then is clipped into place, the bearing inside was moving much easier than the other and if you turned it fast by hand made a grinding noise? so we just hit them with break cleaner and use lithium grase for the whole assemply trying to get some inside the bearing as well, they seem to move with less friction now but one is harder to turn than other (both easy to do by hand). my question is maybe i should have just bolted them in and now i f@cked it up? at least they work fine but i dont want it to fail in short time, or even worse fail while i need 4x4.
