I own a Maytag but have never worked on it. My old GE had concrete counter weights with springs. The spring would break and cause it to rock and roll across the floor. Just pull off the back or tip it up and look underneath to see what they used. You may have to pull the top off as well to get at the springs if they used that set up. Maybe try the parts diagram here and it would show the set up. Under your model.......if you look at "base" it shows #18 as a set of 6 springs. You probably have broken springs as my GE did. I don't recall it being very difficult to replace the springs either.
