Product review (5 stars): Right part. Cheaper than other online stores, almost half the price of Sears parts direct.
So far perfect.  I cross referenced this part using direct parts vendors. Part 8183202 is the hinge for washer WFW9400SW03 even though it is not stated here.
I just installed it 5 minutes ago so I don't know if it will hold up better than the original.  The original rusted or swelled or something and it took the full leverage of the door to open. Made the most annoying fingernails-on-chalkboard sound when moved. This new one moves with no resistance.
There are installation videos online, search YouTube for 8183202.
You only need to remove the screws near the hinge, you can leave a couple screws by the latch because the hinge only needs to slip in the edge. Also note you can remove the two screws at the washer and the door will stay because it has posts on the hinge flange that will hold it until you lift and jiggle it off.
