Kenmore Dryer Noise Model 110.87692100 with Video

My dryer just started making noise. It seems to come and go. It’s a model 110.87692100. Here is a video with the noise. It gets the worse around 3 seconds. This just continues in a cycle, sometimes being quiet for a while.

Here is the video.

Here is a picture of the full SN label.

I trying slowing the drum with my hand (carefully), and it doesn’t make the sound worse or better, but it does change the sound because the speed changes. I tried pushing the drum up down left and right and that didn’t trigger the noise. It’s a pretty fast sound (rotationally), so I was thinking about the motor.

Any thoughts?

Also doesn’t anyone have the repair manual for this unit?
