I just purchased a boat/trailer combo and the trailer needs work. Its really old and has coil springs and is super bouncy. I need to move the axle back to fix that I believe but it's super loud when driving, I hear things that sound loose and clanking around. I wiggled the wheels today and there is a ton of play. Only an axle nut holds the wheel on, there are no lug nuts. There is a gap between the inside of the wheel and the axle; not sure of the bearing wasn't pushed back all the way or what. Should I just find replacement bearings for this or is there a better alternative or conversion without spending a lot of money? I don't mind buying two hubs already assembled if that would work; even though there aren't hubs now.
