Product review (5 stars): It's much cheaper to buy this part here and install ...
It's much cheaper to buy this part here and install it yourself than it would be to order it and have it installed.  That's likely why you're here.  This is a very reasonably priced part.  To do the job, a vise grips and a hex driver set are the only tools you need.  The shipping was quick, and the instructions can be found with a quick YouTube search.  I notice that there are fewer curse words uttered around the house now that I've replace this tube.  Not to mention, I've saved myself from another floor replacement and mold remediation debacle.  Boo to Whirlpool for making a shoddy wash machine.  Thank goodness for being able to buy this from a third party vendor for a reasonable price.
