Product review (5 stars): Priced less than dealer for same quality
Whirlpool used to sell the pump and pump motor separately, but after a string of early failures, redesigned both parts, and combined them into one.  This new pump works great and is quieter than the older design.  Seller shipped the part enterprisingly quick so I was able to replace it right away ad start whittling away the growing mountain of dirty clothes as a result of a failed pump.
