Frigidaire model # FWS1234FS1 Hello, my washing machine is making a double clunking noise during the spin cycle and it gets quite loud. It sounds almost like a car going over a speedbump quickly and its at one specific point on the spin. You can turn it by hand and it will make the noise in the same spot. We have removed the front of the washer and looked for water leaking, no water to be found. We have tried to remove the agitator and we can't figure out how it comes off. This is where we are stuck, if we can get this thing off we can continue looking for clues. We have tried prying it, unscrewing it, and pulling it. And it won't budge. If you turn it counter clockwise it tightens up and if you turn it clockwise it will spin freely. Any help would be appreciated.
