Product review (5 stars): Works great, fixed the problem!
Was exactly what I needed to stop the screaming noise coming from my dryer.  Had the dryer taken apart and parts replaced in an hour or so - I am pretty handy but had never done appliance repair before.  Lots of videos on the web to show you exactly how to do this repair.  Saved a hundred bucks on a service call, or the purchase of a new dryer - all for twenty-five bucks.
