I have had oil bath hubs on my previous boat for abut 4 years now. However, after buying the 2007 X2 with a Sport Boat Trailer, it has buddy bearings. How hard would it be to switch out the hubs and go with Oil bath. Anyone done this yet and if so, is it $$$

I like the oil baths, but I've had Bearing Buddys on several boat, snowmobile, and utility trailers over the years and never had a problem as long as I made sure the rear seals were good and they had a Bearing Buddy Bra on them. What with the cracking and leaking oil baths I've seen reported here, I'm not sure I'd make the switch, if it were me.

If I were going to switch, I'd probably opt for Reliable's Sure-Lube system (http://www.reliabletool.com/products/slgrease.htm) instead of the oil bath hubs. Looks like you could make THAT switch for about $120 per axle. (Northern Tool (http://www.northerntool.com/webapp/wcs/stores/servlet/product_6970_200333678_200333678))

good point. The only problem I have had with Oil Bath hubs are that the set screw starts to come out and slowly drains the 50 weight oil in there. I finally put the orange ATV sealant on each set screw and screw them back in and never had a problem again.

I just don't know how to change out the grease on buddy bearings and it was so easy on oil bath. Maybe that's why I don't like them because they are messy and don't know them as well.

IMHO that's the nice thing about Bearing Buddies or those other pressurized hubs -- no oil change, no leaking, no disassembly to fill them. Just give the zerk a couple of shots of good wheel bearing grease every so often and you're good to go.

I would rather have grease in there than oil. If the oil leaks out, you have a problem. If you lose the grease on a BB (not sure how that would happen) you still have greased bearings. Furthermore, the positive pressure in the BB keeps water out when you dunk 'em. Only maintenance item is making sure the rear seal is functional. If not, it's just as easy to change that seal as it is to fill an oil bath.

Bearing Buddy or Sure-Lube...same concept. IMHO the Sure-Lube is a better design, and it's integral to the hub rather than a pound-on.
