Product review (5 stars): Easily installed repair kit
Since Whirlpool designed my washer using parts with a relatively short lifespan, at least they had the consideration to make those parts inexpensive and easy to replace.  Almost all the parts in this kit were worn on my washer, so I am glad I bought the full kit instead of just the set of dogs.  Replacement was very simple, but be aware that you do need a ratchet with about 10" of extension bars.  There is a very good step by step video on how to install this kit at partselect.com.  Search the internet for the site and then navigate to this kit via its part number.
