Furnace making squeaky noise

My apologies if I'm duplicating threads. Searched all sorts of variations on noisy furnaces and didn't see this exact problem.

My Suburban furnace in a Flagstaff 228 popup is making an unpleasant squelch. It normally starts once things have heated up and continues until the furnace shuts down. I took the attached video right at shutdown, so that all you can hear is the squeak and not the other noises. This was after the burner had shut down.

Seems the fan could be running something, or perhaps the fan motor is about to fail. It's only 2 years old.

Any ideas? Has this happened to anyone else? Is there a sane way to take the thing out and start troubleshooting individual components?

I'm a long way from a trying to solve this myself if possible.
