Broken side gear cross pin retainer. Pull the cover and look for ruined spider gears and a Broken pin.

With the right rear brake drum off is the park brake apply lever seized? Sometimes the park brake shoe lining separates from the shoe and will make it difficult to remove disc drum.

pulleed the pin which has a little play the spider gears have some slack in them and make a some noise when i move them by hand with the pin in place axle shafts removed when i barely pry out on the spider gears it seems to lock up.
