Washer works well except when it goes into the spin cycle it goes bump,bump,bump,. faster and faster. The tub is NOT moving from side to side but it acts like when a load is out of balance. It even does it with an empty washer, (water only). It also "walks" all over the place. I hope it's something easy.

Have you ever leveled it up, from side to side and front and back?

Yes
