Replaced agitator and washplate bolt and washer. Normally this would have been a 5 min job, however the bolt wouldn't come loose. The teeth on the agitator were worn down and the shaft the bolt screws into would turn with the bolt when trying to loosen it. I had to cut out the agitator using a dremel and hold the shaft in place with a vise grip in order to unscrew the bolt. Once the bolt was out I used WD-40 to help get the agitator off the gears. Job took much longer than normal, but I was still able to save money doing it myself. I didn't end up needing the drive block or tub wrench
