Ranger Cool Hubs Maintenance

[joeyblee14]

I have a Ranger Trail Trailer with cool hubs and I am wanting to change the oil in them. I was wandering if anyone knew what kind of oil I should replace them with and how should I seal the drain plug back on the hub. Thanks everyone.

OR "hub oil" available at most truck stops

How to "seal" the plug depends on what sort of plug you have and what it "seals" into.

On my 40' gooseneck with oil bath bearings I have rubber plugs that simply pop into the clear plastic caps.
