I pulled the machine apart, taking off both front and back panels so I could get a good look at everything. Then I gave it a good cleaning. When I pulled the drum out, I realized two of the support rollers where bad, so I ordered four new rollers and two shafts for the damaged one on the machine. Since one side of the drum felt seal was bad I went ahead and replaced them both just like your video showed, easy job, just take your time and there's plenty of sealant. The Idler Pulley needed replacement and worked just like your video showed and as for the belt, it didn't show any damage, but I figured since the machine is apart just replace that as well. All in all, the videos where a great help and our dryer is working extremely smooth and should be any problem for another 11 years.
