I purchased upper pads, lower pads, and tub suspension springs. I was unable to remove the inner tub even after removing the large nut with a spanner tool so I was unable to replace the upper pads. I did replace the lower pads and all springs, which eliminated the walking problem. In the future I might try replacing the upper pads by removing the transmission, which should allow me to remove the inner and outer tubs as a unit thus making the upper pads accessible.
