Purchased new outer tub. Bearings almost gone. I could not remove inner tub as instructed, so I just removed both. I have re installed outer tub. After lots of pulling and penetrating oil I was finally able to remove inner tub. The shaft on the old outer tub feels like it has threads on it. the inside of the inner tube shaft is very worn and rough. Should I replace the inner tub also. And the inner tub is full of water and I can not get it out.
