It sounds like you either have something stuck between the inner and outer tub, a loose tub ring, broken or worn motor coupler, or bad spin tub or block drive. You will need a special spanner wrench (whirlpool manu.) to remove block drive to access outer tub. Go to www3.sears.com for a complete breakdown of you washer. There is no spin bearing on this washer. The unit is very modular and easy to tear apart and rebuild. good luck
