Product review (3 stars): Possibly wrong parts shipped? Looks like they sent Whirlpool 4392067 Repair Kit  (Slightly different wheels and shorter belt)
I believe they send the wrong parts. The wheels are a different color, did not glide as well as the original and I thought the belt was going to break when I did finally get it over the pullies. I saw another review that stated the same had happened to them. The dryer is much louder now than it used to be but it does work....
