Product review (2 stars): Not correct part number for WFW9600TA01 - very difficult to install
I bought this for my WFW9600TA01 Whirlpool Duet Washer that was purchased in 2007.  The old boot had a big rip in the bottom and was leaking badly.  Although Amazon claims this is the correct part number for this model washer, I would not call it a perfect fit.  It fits, but certainly not perfectly.  In fact the part number on my old rubber boot did not match the part number on this one.
It is a very difficult part to replace, solely because of that spring clamp on the outside.  I spent well over two hours on the job, with over half that time spent just on trying to get the spring clamp back on.  The problem with this part is that it does not fit snugly and tightly on the outer edge, so when you attempt to put the spring clamp back on, it pulls the rubber seal off the edge.  It is a very frustrating and difficult process that could be made easier if this were the correct part number for this washer and fit more snugly on the outer edge.  Proceed at your own risk and prepare for several hours of frustrating work.
