Product review (5 stars): A Great Project for a Saturday Afternoon
I approached this project with some trepidation, but with the help of several U Tube assistants I was able to replace the belt and rollers without much difficulty.  The dryer runs great now, no noise and very smooth.  You can do this project in about 3 hours, just put all the screws back in order.  Take pictures that helps as you dismantle your dryer.  I did have trouble with the belt since you need to think like you are at the back of the dryer to get the tension to work, once you do that, its easy.
