2006 Taco 4x4. Bought my Taco last November. After a few month I started hearing a hum come from the drivers side front end. First thought was a bad wheel bearing. The sound got louder over a few months. Turning to the right it was obvious and turning the left it went away. So I had the drivers side bearing changed. My mechanic buddy said the bear had good wear on it.
But the humming has not got away. It's still active when turning to the right and goes away when stealing to the left. I have a 3" block lift on the truck that was there when i purchased it. And now has some front end chamber. My buddy thinks it had something to do with the chamber.
Does anyone have any ideas or suggestions what the humming is or could be from?
