Product review (4 stars): Tough project - Two person job!
Be prepared!  This is not easy to install whatsoever.  I read many reviews and watched several videos...they make it look very easy. Thank goodness I have a great neighbor who was able to get the first spring clasp on for me and stayed while I put the rest of the machine back together.  The first challenge was trying to figure out how the door gasket went on.  It felt too large at first.  Once that was finally on, the spring clasp on the tub lib was major!  My model has a plastic panel that fits over the door gasket but that is never shown in any online videos so I was on my own in figuring that part out.  Once on and all put back together, the part works great.  No more leaks or smell when I open the washer.
