Chris is that a sealed bearing? if so the torque is over 200 ft lbs. You will need 3/4" drive sockets and a 4 foot bar to extend a large breaker bar to get the hub nut off
I normally have to stand on the end of the bar to get enough leverage. Normal 1/2 sockets aren't enough so I borrow some big stuff from the tank workshop at work to do the bearings. I snapped a 1/2 breaker bar in January trying to get the hub nut off.
Post a photo of the nut without the hub cover and we will tell you what you have.
