2008 4Runner drivetrain humming-droning noise

Hi Scotty, Love this channel, great stuff !

Got a 2008 4Runner with a drivetrain humming-droning noise.

Had it looked at by a garage owner I've known since we're kids, good mechanic that went to college for it years ago, and he says it's probably nothing to worry about but its nerve-wracking not knowing what causes it and just aggrevating to listen to. Any speed it's the same noise. Doesn't speed up it's just a constant droning hum..

Any ideas ?

Thank You and keep up the great videos...

Find out where the noise comes from, specifically check the rear differential. when was the last time you change the differential fluid?

In addition to @yaser ‘s advice, try this method to pinpoint the noise -
