    Hello, looking for just a little guidance on topping off the oil in the hubs. I bought this trailer approximately 60k miles ago, and even thought i get the trailer greased up often, I never did anything with the hubs. I started noticing oil buildup around the them and i was wondering what can i do about it myself. All four hubs have oil deposit, some just around the plug and the others around the seal and the plug. I'm looking to just top off the oil in these hubs for now, how would i go about doing that and what oil should i use. From the look of these pictures, is this something that needs to be addressed immediately? Thanks on any suggestions.

    Looks like grease hubs. I wouldn't worry about it. When you start seeing grease all over the rims is when you need to worry.
     
    Straight Stacks, Fliner2000 and mhyn Thank this.

    A guy I know has them types of hubs on his trailer and he says he always feels the hubs or takes a temperature reading on them from a temperature gun, they're on amazon for about 50 dollars and a real good thing to have, anyway, he says they need service when of course they leak, or if the temperature on them gets real real hot.

    I've been away from trucks for a while and we would rarely see the grease style hubs so I'm not 100% sure. My best guess would be wheel bearing grease.
