Speaking of that, my dryer roller wheels took a dump. They somehow siezed up and wore a flat side on the wheel. Imagine that of all things. I just changed them. (Wheels that ride on the drum.) Don't know why but I suspect the lubricant I used hardened up when I installed them. And the tolerances coupled with that hard lubricant I used caused them to sieze somewhat. So I ordered a new pair. In the meantime, I did sand down the inside of the wheel and the shaft it rides on, sprayed it down with liquid lubricant and it is freed up, turns great, only problem, with the flat side of the wheel, causing a definate tumbling noise. So waiting on my new rollers.
