Product review (5 stars): solved my problem.
my washer was making a GRINDING noise when washing (not spinning or draining)...........  This solved my problem.  Took about 10 minutes to install..  Washer sounds like it NEW again, maybe it will last for another 4 years. :) I think my problem was that the inner plastic part was rubbing against the inside ring part making a noise like the washer was dieing ... eventually, the noise got so loud that it was unbearable to use the machine. Suggestions were to tighten the Nut, but that seems to only work if you catch the problem early, the noise my washer was making has been going on for a few years.  It was a Maytag Centennial ((commercial grade LOL) (plastic parts)) but 20 bucks and 10 mins, who cares.  I can deal with that.  So far so good!  Hopefully I can get another 4 - 5 years out of it.
