Using the video on this website, I was able to properly disassemble the dryer and determine what failed. One of the bearings on the rear drum roller was seized and the roller itself was jammed between the drum and the rear bulkhead causing the noise. I took the time to inspect the other rollers and belt before ordering any parts. Ordered the two rear drum rollers overnight and they arrived next day as promised. Installed the parts and dryer is working as designed. I have used this website and their instructional video before to replace the heating element. It has saved me from having to purchase another dryer multiple times now. Great website and service provided.
