Product review (5 stars): Sure enough it worked like a charm
My dryer (Whirlpool Duet WRD9200SQ1) was squeaking so I found this little gem.  Sure enough it worked like a charm. The pulley was no longer spinning.  This particular model requires most of the dryer to be taken apart so it was a fair amount of work.  Video's are found online to help.  One can do most of the work but two helps you put the dryer back a bit easier.  Great product - thanks for offering it !!
