Product review (5 stars): Best thing I've ever bought on Amazon
Man, I thought i needed to replace my 15 year old washing machine, but no... this $5 kit plus a youtube video and I fixed it in 10 minutes.  Best Amazon purchase, ever!  Also, my parts were genuine Whirlpool and the clutch dogs were rubber.  The kit included all the parts plus some extra stuff in case you really wanted to go deep on the rebuild.  Not me, I'm lazy and just replaced the dog and the "doghouse?"
