New drive block was very hard to remove from shaft (shaft very rusty) made my own flange nut removal tool, soaked in (Blaster removal spray overnite) still hard to remove, very little room to swing a hammer but persistance paid off, got it off. Then had to put 19" 2 x 4 inside tub and another on top of frame, tie with rope and pry up tub, had wife hold pry bar while I whacked drive block with long skinny pipe and hammer. Finally tub came loose from drive block and shaft. After a LOT of cleaning, reassembled washer, working fine now. I followed the installation video which was a little different than my washer but workable.
