How to remove this hub?

[rvpaker]

I have one of these in my tow dolly. There is a slight movement in the wheel. Is it normal? If not, how does this come off the frame? There is no axle. This thing mounts to a body, giving a rotating flange for wheel mounting. https://www.etrailer.com/Accessories-and-Parts/Demco-RV/DM04369.html
Thank you.

Unit bearings like that often have just a slight amount of movement in them. Same goes for the bearings in many of our trucks.

There should be 4 bolts that hold it on with that square rear flange. I would think that it should have no movement in it. Are both sides equally loose? Is the looseness in and out movement or up and down? How many miles are on it? If the miles are high it might be time to replace both of them. It may be an issue like some unit bearings in our front wheel drive vehicles, some dont have a long life.

Appears to be sealed unit. Must un-bolt from frame
