Watched your videos on repairing different parts of the washer such as, the tub, agitator, tub balance springs. The problem was found when I removed the agitator. The neck of the tub was almost totally rusted through. Had I had a spanner wrench it would have been a lot easier. Several sprays with GP Blaster penetrating oil helped loosen the nut but punch and hammer damaged the nut to where I didn't want to reuse it. Next problem was getting the basket drive block and tub loose from the gearbox shaft. More GP Blaster, hacksaw and chisel finally got it loose. I was surprised at how packed the rust /dirt was around the neck of the tub holding it on.
