Looks to me like the wheel studs need to be pushed out.
They will be a shallow spline shank that are pressed in from the other side.
A small porta-power would be the easyest.
Use a nut screwed on the stud almost all the way so the threads do not get damaged.
The pry bar may work, but don't get your hopes up.
I have also had luck putting a spacer (the right thickness)in as a backing plate and then using the stud nut to push the stud out, by running the nut off the stud.
Make sure everything is lubed well.
Hope this helps and not confuse.
Also keep us up to date on how you get it apart.
