Product review (5 stars): Replacement for Idler Level for Amana Dryer Model NDE2330AYW
My 10+ year old dryer, Amana Dryer Model NDE2330AYW, was working fine but emitted an exceptionally loud screeching noise when operating.  Through internet research, determined the bearing in the idler level was shot and needed replacing.  Ordered this replacement idler level from Pandora's OEM Appliance Parts and it arrived earlier than expected and in a sealed plastic bag indicating it was an actual Maytag OEM part (Maytag owns Amana and apparently many parts, including this one, are interchangeable between the brands).  Followed the instructions on this video - youtube.com/watch?v=8AtOYoABVp0 (search youtube for "Whirlpool Dryer Idler Level Replacement") - and the repair was completed in less than 15 minutes, and the screeching is now gone.  One note about the video - my dryer has screws holding the dryer top to the body, so do not try to pry the top off the body of the dryer with a putty knife or screwdriver - you need to remove the front panels first to expose the screws holding the top lid to the body.

Can only imagine what this would have cost had a repairman been called - at least $200 I'd estimate.  If you are even minimally handy, you should be able to complete this repair yourself with little effort and time, for short money with great personal satisfaction and hopefully many more years of useability for your dryer.

As an alternative you could buy the idler pulley (the wheel section of the part) alone, as it comes with the replacement bearings, but then you'd have to affix it to the idler lever and that looks like it would be a bit of a pain and would save you only a couple of dollars - not worth it for me.
