Product review (5 stars): Works great and well worth doing this fix rather than buying a new washer.
Product works great!  Washer is really quiet now!  The bearing press tool will probably save you some time and frustration, but you should also be prepared to deal with a lot of rust and corrosion if you have an older washer.  I ended up having to saw and chisel off the old shaft nut that was welded on with rust and knocked out one of the old bearings in pieces because it had basically exploded.  Difficult job on an older machine, but felt good to watch it all run like new after it was done.
