I just changed the drum & drum support wheels on my newer LG electric dryer. It was easy. Did a Google search for the symptoms, watched the video, found the parts on-line cheap and did it myself. Runs better than ever now.
Update: I forgot to mention that I lubricated all the bushing surface of the new wheels with Synthetic Disc Brake Grease. The kind with Moly, PTFE, & Graphite. They were dry when I took the old wheels off. Only one of the wheels had become seized on its axle and flat spotted. It didn't take much lube to get the job done.
