Product review (5 stars): Very satisfied with this purchase, and the dryer's been running since the day it was installed without a squeak.
By following the youtube video and purchasing this kit, I saved an estimated $200+ on a service call to fix my gas dryer.  Truth be told I probably only needed the little white pulley, but hey as long as I had the entire dryer disassembled, why not replace all the soft rubber bits?  The cost in time and hassle for me to take apart the dryer pales in comparison to the very reasonable cost of this product, which by the way did appear to be the manufacturer's repair kit and not a 3rd party knockoff.  Very satisfied with this purchase, and the dryer's been running since the day it was installed without a squeak.  Highly recommended.
