Product review (5 stars): Man I can not tell you how happy it is to not hear a terrible screeching noise ...
Man I can not tell you how happy it is to not hear a terrible screeching noise coming from my dryer and being able to hear it outside of the house... Yeah it was that bad.  So I got the washer and dryer when I purchased the house this summer and they both looked in pretty good condition until we actually went to use them.  Did a little research about the noise and purchased this kit.  Putting the kit in really is easy but you need to disassemble the whole dryer in order to do it (at least on my Frigidaire dryer I did).  So just realize if your not to mechanically inclined you may want to have someone do this for you but so far I am very happy I don't need to grind my teeth while running the damn dryer!
