Product review (5 stars): My HE5 dryer had a loud banging like noise when it was on
This fit my Kenmore HE5 Dryer.  My HE5 dryer had a loud banging like noise when it was on.  I did not use the idler pulley that came in the pack but instead ordered the one already on the bracket. The idler pulley and bracket I purchased from Amazon was (Whirlpool W10837240 Bracket) and only cost around $10 so it was worth not having to take apart the old one and the replacement job was so much easier.  Recommend finding a YouTube video on this repair.  My machine was the HE5 dryer but I could only find the YouTube videos for the HE3 dryer.  The models are so close it was not too difficult to follow and do the tear down and repair.  If you can do repair work yourself you will save lots of money buying this kit and avoid calling in an expensive repairman.
