Product review (5 stars): I don't normally tackle this kind of job, but this turned out OK
Easy enough in the end with the right tools and watching the excellent youtube tutorials.  You will need a pipe wrench or vise grip with curved jaws to hold the shaft while using a wrench to loosen the shaft nut; I fiddled for a long time with a non-curved vise grip, and it wouldn't get enough grip to keep the shaft from turning.  Also, note that the stator is not held in place only by the screw, there are magnets holding it on, you need to pull on it after removing the screw.  The repair was cheaper than a new washer, we can now look forward to more years of clothes twisted up into knots and unbalanced loads.  Try Charlies soap powder if your clothes don't t seem all that clean or fresh to you, it rinses out clean so they don't smell like compost water any more.
