    I have a constant hum in the drivetrain over 60mph and gets worse the faster you go. I have replaced the u-joints. Maybe driveshaft?

    could be a wheel bearing, does it have a specific location?

    That is a possibility. I just ruled that out because there is no noise at slower speeds. Sounds like it is coming from the back. Thanks for the feedback

    Yeah I might be kicking the wheel bearing

    jack it up and turn the wheels slow and listen for noise, grab wheels shimmy them see if there is play...
