Kenmore commercial washer 110.2011200A off balance and spinning violently. Opened up the unit and found a bad balance ring. The clips on this ring were gone and the ring was just spinning around. The balance ring is a ring that goes on top of the drum that has a liquid (water I guess) in it. As the washer agitates and spins the water in the ring helps it stay balanced. I replaced the balance ring and the problem went away.
