We will never put near the miles on our tat as we will our tow vehicle. I think that grease is fine.

Thats good to know, I have the disc brakes, was wondering about a change. I will stick with the grease I use . I have heard guys bragging up the oil bath setup, guess its not what its cracked up to be.


It is if the internal volume of the axle/hub is large enough and the seals are the correct ones. One of the engineers cited "gallons" of oil for 18-wheeler axles vs. a pint for our RV hubs. That's a lot more oil to absorb and dissipate heat and a lot more space for expansion.

Wheel Bearing Grease, I'm good with pulling wheels once a year to look at bearings and repacking.

My son had oil bath on a saltwater boat trailer. No thanks.
But...I would love to have Vault hubs on the 5th. I have them on my saltwater boat trailer. Bought new 2014. No maintenance yet. Dexter owns Vault, I don't get it.

My Kodiak kit came with oil covers so I tried it. I ran the initial oil for 5 years, no problems, and I changed seals and oil in 2019. After 5 years, I could still see the machine grooves in the rotors... I'm easy on brakes.
The new oil is staying a LOT cleaner, now that my old bearings and the new cups are run-in. I run the bearings at zero to maybe a gnats butt of clearance... I'd prefer zero but some of the locks won't let me set the nut that way. I ran to Phx. last Oct. 75-80 mph and the hubs were 94-98 degrees.
Each hub took 3 oz. until I poked a tiny vent hole in the middle of the rubber plugs and added another oz. with a syringe.
Oil always worked good on my trucks and trailers, when I was in that business. I used Stemco oil covers on the front truck axle and the trailer axles. I use 75w140 syn. Craig

First, seals made for greased hubs will not always hold oil.
For a vehicle that gets a lot of miles, grease will increase fuel consumption.
For years I maintained a storage trailer for a builder. It would set for months between moves. I packed the bearings on it so did not need to worry about leaks/contaminated brake shoes.
Can't see much advantage to oil bath bearings on RV trailer, except bragging rights.
