Hello -

I don't show a difference. Have you sprayed penetrating oil and let it sit? Is it corroded bad?

In my diagram it just looks like the 4 bolts are holding it on. Again, is it just corroded really bad?

The four bolts (nuts) you removed just hold the backing plate to the axle. To remove the hub, you have to knock out the large center cap from the hub. Under this cap will be a cotter pin and a castle nut. Remove the pin and castle nut. This will expose the outer bearing. Give the hub a "rap" and the outer bearing will pop out, remove outer bearing and screw the castle nut back on the axle shaft without the cotter pin. Give the hub a sharp pull outward, and the inner bearing and seal will remain on the shaft. When reassembling, be sure not to over tighten the new bearings with the castle nut.
