Undo and remove the shock, and spring mount plate. This will relieve some of
the tension in the wishbones. Heave the hub assembly up and down a few times
to see if it will free up the bolts.You might get the bolt to start turning.
I normally use an old knackered torque wrench to get the leverage.

If that still doesn't work, remove the bolt securing the leading wishbone to
the chassis bracket, and try cranking it up and down. With luck it will free
up and can be removed. Remove the back wishbone mounting bolt from the
chassis bracket, and repeat. If all else fails, you will end up unscrewing
the trunnion complete with two wishbones.

I have found them to sieze steel to bronze, and have had to cut one out with
an anglegrinder. That was an extreme case, and they normally come out with a
little persuasion.

Good luck
