I did one tuesday, 3 year old machine and the tub was stuck pretty good. What I do, is take in some rustbuster. Pour it in spline, let it sit a couple of minutes. then Pull up and down. then, I pull up on inner tub with one hand, and use my 5 lb short hammer and pound shaft. Gets it right off. doesn't matter if you ruin shaft, your replacing it anyway. That cabrio tub removal tool is interesting, but I haven't had the need for it yet. Have 2 more of these scheduled for next week.
