I havent had the wheels off yet, but I need to add a little oil to my hubs. What kind of oil do I use and do I pull the wheel to get to a fill spot?

Chris Sunkin

At the likely risk of sounding like a smarta$$...


...you use hub oil.


Any truck stop, dealer or service garage.


Doesn't the bearing cover have a little rubber plug in the center?

KNOT-RIGHT

its just 80-90 gear oil there should be a center rubber plug
pull that off and there is a line for the level it is about a 1/4 of the way up. They dont require much oil.

I am refering to 10,000# HD dexters

80-90wt gear oil for use in Ky area if you are gonna run out to Arizona or any hot climate go with 180wt gear lube. Same thing little rubber plug in the middle they realy don't take much. iIf you over fill em it will come out when they get hot.

Mine have an allen screw @ the base area. I dont need to remove my wheels but I do jack up the trailer to drain the oil. Refill it with 80/90 until the sight glass is full then tap on the hub to expell any air ,top it off & re install the plug . Also paint a bit of touch up paint to seal the plug.

Thanks

Yes, very much so- only issue is that grease won't leak out if you lose the cap or crush it. There's a reason all the big trucks use oil bath hubs.

You can use other oils but why not get the one made for the application?

Downside of the wet hubs is if you blow a seal your screwed. If you notice the larger fleet trailer will have grease.

If you're out blowing seals, you have bigger problems than trailer bearings
