Jackson -
This may be what caused the leak in the balance ring in the first place...something hitting into it.
The entire tub assmebly, if you grab it from the outside, should be able to be pushed up and down on those struts that sit underneath the machine. It also moves from side to side on the 4 shocks that are mounted to the exterior of the tub. That seems to be fine on your machine. If it won't move up and down, something's not right. Now it does not move up and down easily, but it does move. Those struts maintain the tub height against the rubber seal that runs around the interior of the tub, under the lid. I think it's beige in color, and you can see it when you open the lid on the machine. Those stuts keep the tub from dropping to low under load, and allowing water to splash out over the side, as well as just keep the "ride height", if you will, stable.
You may still be looking at a complete disassembly to get to the bottom of it. I'm at a loss, except to think that maybe the spin shaft is somehow bent?
You have checked all 4 of the shocks that are attached at the exterior of the tub around the machine? I'm sorry that I can't give you a more definitive direction to look in, but I'm stumped. I'm gonna check my Calypso manual tomorrow tonite and see if maybe I've missed something. That machine is too pristine to give up on!!!
