Product review (5 stars): Worked!!
I went to a local place and they wanted to charge me $20 for the parts. I told them I can get it online for way cheaper and they went down to $15. Other local repair shops charge $45-$65 for repairing agitators. I fixed it in 10 minutes with the help of my girlfriend. (Her hands were smaller than mine and of course she is great at supervising and telling me how to get it done!)
