So the Bronco has a Drone to it since I bought it. It's almost deafening at about 60-65 mph. I thought it was tires, which I replaced. Then the muffler, which I have determined it is not, by shifting into neutral at 70 on a hill and it changed nothing. I'm thinking it's somewhere in the drivetrain, maybe the u-joints in the driveshaft. I will also check the bearings.
