After finding my dryer on your site, I checked the parts that might be the problem. After reading the descriptions about what could be the problems, I ordered all the parts to cover each scenario. That cost was a lot less than a repairman visit and the parts were easy to install. The videos definitely helped with the installation and my dryer is quiet again. I'm not sure which part fixed the noise but for the cost, it was worth replacing what I did as I now have new parts throughout which will last. Glad the noise is gone. Thanks for your help.
