I hear a drone noise (or loud humming) when I drive my 2010 Toyota Highlander.
Asked by nanbarker Jul 18, 2017 at 09:54 AM about the 2010 Toyota Highlander Base
Question type: General
I have had my mechanic look at it. He says the ball bearings are fine. We cannot figure out why this noise commenced. It's been over a year. Any suggestions or thoughts on what could be causing this?

Check your differential oil levels front and back. And the transfer case oil too. It might be abnormal tire wear or low on air. I hope this helps.
Check for uneven wear on your Tires. A bad strut(s) can cause cupping of the tread on tires, resulting in a droning sound that gets louder the faster the vehicle is driven.
Did you ever get this figured out. I have. 2015 with same symptoms
