Mystery train like noise when dryer came on

My Repair & Advice
I couldn't quite pin-point my noise. It was a 'chugging', rumbling noise, and somewhat irregular. Definitely not a 'screeching,' and the belt appeared fine; most of the online videos I saw assigned a "chugging" or "train" noise to the belt or tensioner. I tried the 'maintenance kit' (bearing, belt, tensioner, felt), the overall noise was better, but the chugging noise was as bad as ever. That left only the blower and the motor as moving parts.
Sure enough, when I looked at the fan, the fan had become detached from the fastener, and had slipped forward, spinning against the edge of the housing. You could tell the front edge was wearing away -- and the foam seal was worn where the blades rubbed against it. And the front of the dryer was very hot; a potential safety hazard, really.
Now I've basically rebuilt the internals, between the maintenance kit and the blower housing. But, my wife says it is so quiet now, she has to remind herself that it's operating correctly. Here's hoping we get another five to ten years out of it.
