Product review (5 stars): Exact Replacement.
Piece of cake. If the agitator doesn't agitate, buy this part. I guarantee you will be agitated in no time at all. Honest, putting the part in is easy. Getting the agitator free to replace the part... well.. that can be fun. But why would you call a washer repairman to charge you a hundred bucks to replace a five dollar item? Go for it! Life is all about learning new stuff.
