Did you remove the two screws that hold it to the hub?? If so. Try to free up the two adjuster cam bolts on the backing plate .
If those are loose too... Pb blaster and a lot of pateince. If all that does not work. A pulled will but you need to go very slow and tighten it. Tap all around with a hammer. Tighten a little more. Tap again. Patience is the key. Good luck. I got juck with my 56 cj5. Every thing just pretty much fell apart...
Another closer one.... It shows two of the three.
