Top portion of agitator wouldn't turn.

First I removed the top cap on the agitator, then I removed the second cap inside the agitator. I moved the agitator with my hands and saw that the "dog ears" were worn and no longer touched the agitator and couldn't move it. I then used a nut driver to remove the nut that held the top portion of the agitator onto the bottom portion. I made a note of the worn parts, got online at PartsSelect.com and ordered the replacement parts. A few days later the parts arrived and I repeated the above process in reverse using the new parts. It now works like new!!! It wasn was very easy. Thanks!!!
