Noisy Blower/Heater Fan

[landtoy80]

I have a noisy blower/heater fan. It sounds like a bad bearing.
Is there a bearing in the fan?
Its not a leaf as it has been this way for a very long time but getting louder.

Maybe it's Whitie? TJDIV's white squirrel. Had paper in mine for awhile till I got fed up with it one day.
