Oil bath trailer hubs
 

I think they are marketed as Turbo Lube hubs.Anyone have any experience with them?

The only ones, I know of are http://www.bearingbuddy.com/

I am not sure, if that is what you are lookinf for tho

These are what I'm considering. http://www.championtrailers.com/turbo_lube.htm

Nevr heard of them, but it seems to me that the oil would be more easily effected by a small amount of water intrusion than grease would.

I spoke to one of the Owens brothers of Owen and Sons Trailers. He doesn't like them. He said if they get a crack or somehow lose the oil in them, you are done. Whereas, if it is a grease bearing, even if you lose the buddy bearing, you are running with a greased bearing. You can go quite a way with no buddy bearing.

Oil filled hubs
 

I've had to deal with them on a couple of trailers: the concept is nice, but the reality is, that they can, and do occasionally leak their lube out(usually cracked or loose plastic bearing cap). I personally prefer the safety factor of the greased hubs.

I have used them on many trailers. Give me grease anytime. As stated above, there is no margin for error. A loose or cracked cap, bye bye oil and bearings.

FWIW, I switched all my boat trailers to Amsoil grease after experimenting with it on one of em. Runs cooler than anything I have ever used. just put 4000 70+ mph miles on a brand new boat trailer using it, and the hubs are still tight on the axles shafts..

Thanks very much for the help.I'm definitely going to heed your advice and stick with the grease!Hope the weather cooperates with the rest of all your boating season!
