Product review (5 stars): Saved me a bundle over have a repairman do it
The seal kit arrived quickly and exactly as described. This combined with a new shaft bearing (Whirlpool Part Number 6-2040130: TUB BEARING) and install tool ran me about $75, less than what it would cost me to have a repairman drive to the house. It's not a difficult job and anybody with normal mechanic tools can do it. Youtube has several instructional videos to guide you.
