Product review (5 stars): Know your model number
We originally ordered the wrong part for our dryer. I searched on sears parts website and that was a bust as we needed up with the wrong part that it showed for us to buy.  We were able to find the right part right away on amazon!!  Once we received this part it was easy to put on.  Worked for our Whirlpool dryer model# WED6400SW1. Replacing this part fixed our squeaky dryer!!
