I took it apart and checked the website for possible problems and inspected the parts most likely to fail. I found the drum roller bearings were rough and the blower wheel was wobbling on the shaft after inspecting the belt. I decided to replace it as well. after all, it is 35 years old and things are due wear plus it needed a severe cleaning and a new lint filter. With all the parts replaced and put back together it was very quiet and drying time was reduced it works as well as new. It was an easy job with the video's you posted and I was confident in being able to do it. Thanks
