Now that the axle is finally out you can remove the bolts that hold the inner bearing housing to the frame.

To remove the outer bearing you have to remove the three nuts that sandwich the bearing between the flanges. Then remove the outside flange and you can just pick the bearing out by hand. (This picture was taken out of order just to show you which nuts to remove)

Take the inner bearing housing and place it on a vise so that you can tap the bearing with a punch to get it to rotate away from the housing. Note: After I wrote this article Dan from Recreative Industries gave me a good tip on these bearings. He said to put the flange in the vise and use a pry bar inside the inner race to rotate the bearing in the flange. Do this when removing the old bearing and when you install the new one. That is a better way than I have shown here.

Once the bearing starts to rotate out flip the housing over and turn the bearing until it can slide out of the reliefs on the housing.
