Product review (5 stars): Idler has a Wheel....
Got the kit quickly.  Only difference was the replacement Idler had a "wheel" where the original did not. Works fine if not better!  Found video on YouTube to do the work myself but do yourself a favor-have someone give you a hand to hold the dryer barrel when you put the new belt and the front cover/door on.  Only took maybe 25 mins and $40.00 to replace these items and also a new door switch.
