Noisy vent fan

Thoughts on how to fix this noisy vent fan. Most noise seems to happen after you turn it off.

Here is a video to hear the sound.

It'd either grease and grime on the blower wheel rubbing on something or gummed up motor bearings. Pull out the filters, remove the fan and spin it by hand. That will give you an idea what's making the noise.
