To get the outer races out, most hubs I've worked on either had 2 spots where you could get at it with a punch and drive it out, or there was just enough shoulder to stop the race but also enough clearance to get at it with a punch. If you can't get it this way(Sometimes takes ALOT of pounding) You can try running a bead of weld around the race and douse it in water IMEDIATELY. It should pop right out, but I've never done it this way. Next time I think I'll try it though. As far as the tapered roller bearings themselves, they should come right out. If the hub sticks onto the spindle w/ the nut removed, give it a quick pop or hit it with a rubber hammer. All hubs I've taken off came right off with out any fight from the spindle. When putting it back together, it is best to install the outer races w/ a press so you have steady, even pressure. If you don't have a press, you can use a bench vis if it will open up far enough or use something softer like a wook block, big enough to cover the entire race, and drive it in with a hammer. Once in to a certain point, you can drive it in the rest of the way with a punch, working your way around it with every hit (ussually 180 then 90 from the last hit) Before you put the bearings in, make sure to pack them. This can be a messy job so make sure you have plenty of rags on hand. Take a handful of automotive spindle grease, or even better for the farm use is grease for boat trailer hubs. You take the bearing and skim the edge of the grease in the other hand with the edge of the bearing. Once it ooses out the other end of the bearing, rotate it and repeat until you worked your way around the whole bearing. After the hub is in place w/ the outside bearing, put all the washers/ nut back in place. I ussually tighten it down until the hub won't turn anymore, then back it off until it spins freely. If the hub doesn't have a grease zurk in it, I'll drill a hole in the dust cap (1/4-28 threads) and insert a grease zurk there. Every year when you pull it out give it 5 shots of gun grease, and you're set.

In a hay wagon you could get by using the old one if it's not scored/gouged or otherwise worn out. Good Luck!!
