Product review (4 stars): Whirlpool Needs To Revisit Their Parts List
My dryer began making a screeching noise.  After countless YouTube videos and speaking with dryer salesmen I decided to fix the issue myself with this kit that Whirpool says should work on my machine.  The culprit of the noise was the pulley wheel. The pulley wheel in this kit is not the same on my machine.  It's so large that it rolls against the drum.  The screeching noise is gone but you hear the plastic pulley wheel rubbing against the drum.
