Currently installing a set of 4 kodiak dacromet rotors Should i install a oil bath setup or just stay with wheel bearing grease?

Personal preference really. I've always used greased setups with bearing buddies, however my current trailer came with Vault oil bath axles. Also came with a 10 year warranty, impressive to say the least!

I always say, they will all fail at some point and all run reliably when cared for properly.

I converted from drums and greased hubs to disc's and oiled hubs about 6 years ago and have been very happy with the setup. The oiled hubs have not leaked a drop so far and run cooler than the greased hubs with Bearing Buddies ever did.

Stay away from the oil bath hubs! I had a triple axle Loadmaster trailer that came with them from the factory. The dam things leaked from the first day. I was told the problem is towing the rig to the ramp and then dumping hot hubs in cold water. It causes the pressure in the hub to drop and ingest salt water. I failed about 3 bearings and decided to get rid of them and go with grease bearings. No problems since. They work great on trailers not dumped in the water.

The only problem I've seen with them is if the trailer sits for long periods of time the top of the seals tend to dry out. I don't see where they are any different from greased hubs when dunking into water while hot. Both will contract when cooled but neither can suck water in unless there is a problem with the seal.

The main problem I would have with an oil bath hub is if for some reason, I lose the hub cover. If I do this on the greased hub, I can continue driving, even if it throws a lot of the grease out. With the oil bath so much.

I was told if you let the trailer sit for a while the top part of the hub that does not have oil on it (half full) well rust. This was the local trailer shop telling me this but mabe they get a higher mark up on the greae set up

Isn't that what I just said?

I load an EZ-Loader trailer in saltwater. I went from drums and grease (which I redid each spring and always had the problem of the shoes bonding to the drums) to LiquaLub oil bath. This eliminated the rusting bearings issue but I sill had the shoe issue and the after-market oil bath gave me problems with leaking and the plastic covers breaking. I then went to disk and oil bath (Kodiak kit ordered directly from EZ Loader) and for the past 6 yrs have been problem free. I do strongly suggest that if you change to oil bath, change out the seal sleeves also.

Had oil bath hubs on my last rig. Always thought I should change them out for the grease versions but in three years and maybe 5,000 miles of towing they performed perfectly.
Hard to accept new technology but it worked great.

The oil bath hubs were originally designed for over the road tractors trailers and heavy equipment hauling trailers. I really don't think you will see the benefit of the oil bath hubs unless you are hauling extreme loads. For your application, I would stick with the grease. Additionally, if for some unforeseen reason you loose a dust cap you can still run with a greased hub. Yes, it would make a mess running without a dust cap but at least you could get to location to make repairs. If you loose a dust cap on oil filled hub, which usually screw in but I have seen them come off or crack, you are dead in the water. Go with premium marine rated grease and you will have no issues.

I have been told that if you have oil bath you should carry an entire complete hub as a spare. If you have a failure on the road, you would need to install the new hub to get going again. I have no first hand experience with oil bath but this is what I was told by the manufacturer of my trailer when I was buying. I trailer 100%.

My trailer came with oil bath hubs and I loved them until the clear caps started cracking and leaking and then one did come off. As soon as I experienced that I switched them all to grease.

BTW - My trailer would sit for long periods so I would jack it up and set it unloaded on blocks. I had heard of the seals drying so I would rotate them when I walked by. That did not seem to help. The oil bath would spin alot easier and longer than the grease ones will.

You should do this regardless of the lubrication system.....

If its not broke, why would you replace it. I know your doing a change out but still. Has Grease done you well in the past? I repack every season and have had no issues. Hope I didn't just jinks myself. To each his own:)

I'm running an EZ Loader trailer now for the past, almost, six years and averaging 20,000 miles a year with oil bath hubs. I was apprehensive about them but they've been just fine. I still have the original bearings in place as well and everything's running perfectly. NO, I don't dunk my hubs since I'm running a roller trailer. My average charter includes a 200 mile round trip, day after day....

Thanks for the insight.. My trailer sits during the week then makes the 2 mile trip to the local lake.. About 3 times a year i tow the boat to the bay which is around 135 miles one way
