Washer wobbles and walks

My washer wobbles and hits the sides of the machine on spin cycle. It sits on cement and has been leveled properly. I inspected the inside by removing the front panel and all looks fine to me. No worn out or broken gaskets that I can see of. The tub moves easily around when turned off.
Would changing the 6 suspension springs be the next step in a possible solution to the washer wobbles?
