My washer "walks" a lot and acts out of balance. Would this be the shocks or the adjustable feet not being correctly adjusted?
You will want to check the levelness of the unit to make sure that it is leveled. Also check the feet to make sure that the rubber on them are not damaged. If the rubber is damaged this could cause issues with walking. You can check the shocks by pushing down on the tub and if it springs back then the shocks are ok.
