There is a thumping noise when washer spins. The noise gets louder the faster the cycle goes. I took the back off and removed the belt and turned the large pulley by hand. Every turn you can hear/feel the thump once a turn. Would this be the bearings or something with the drum?

A knocking noise can be a loose tub weight. This would normally be worse with heavy loads and would not be present on spin with no washing in. This is because the knocking noise is caused when the tub (or outer drum) shakes about on spin. Without washing inside the drum the tub doesn't move. Another symptom of a loose tub weight is grey concrete dust under the washing machine. Warning: These days most washing machines have plastic tubs and over tightening a tub weight bolt can easily shear the bracket resulting in a new tub being required. Try loctite. Often, once a tub weight has come loose the plastic tub is damaged anyway especially if it isn't caught early enough

1) bearing have collapsed about to lock up the drum when you turn it.
2) or one of the spider assembly arms has broke away from mounting.
