If you have gotten to the point of getting access to basket and tub of your 417 washer, then you are taking on a very aggressive DIY project. With that said, the basket is held onto the rear half of the outer tub simply by the bolt to the main pulley. Remove the bolt, remove the pulley, and the basket shaft should slip right out of the bearings of the rear tub. I should add though that it is unlikely that you have something that has gotten in there that is retarding movement of the basket. I would guess that you have more of a bearing problem. Simply shining a light around between the basket and outer tub should confirm that there is nothing in there, since you have access to do this with the front tub removed. Go ahead, remove the pulley and bolt, and if the basket comes out, then check everything out. If it doesn't, don't try pounding it out; stop there and go to plan B, which is a new basket and tub assembly. You are in luck: Frigidaire makes it easy by producing the whole assembly all put together for you; front half, back half, basket, new pulley all together. I can get the part number for you if you want. Keep in mind though that the retail price of this assembly may lead you to want to replace the whole machine.
