Product review (5 stars): Whirlpool Quiet Partner replacement
Very Very happy with this part!  Had a God awful sound when I would run the dishwasher.  Was going to have to replace till I found this part.  It was cheaper than the local repair shop by 15 dollars.  Sorry local economy.  It fit in perfectly.  Along with youtube video instructions I found, this done in 2 hours.  It is quiet again and I have hundreds of dollars still in my pocket from not having to call a repair company or buying a new dishwasher.  I highly recommend.
