The amazing video on the AppliancePartsPros.com web site, walked me through the process of taking my dryer apart and replacing the rollers. The only problem I had was that I thought it was one defective roller, only 3 years old, but it was two. When I ordered the second roller they held up my order thinking it was a duplicate. Just order two or even four to start with. Lesson learned, if one is bad, two are bad. It isn't that much work to take it apart but I should have ordered two to start with.
