Here's a suggestion: Jack the rear end up (put a jack under the pumpkin and put some jack stands under the control arms to straighten out the axles). Start the car and put it in 2nd or 3rd gear. Then you can get out and listen for the noise while the wheels are turning.
I did this with my kid's Jetta this summer. It became apparent that he had a bad wheel bearing. When the car is jacked up like this, it eliminates road and tire noise so you can easily pinpoint the problem.
Be careful putting the control arms on jacks. You don't want to break a control arm. But you don't want to have the car running in gear with the wheels just hanging down either.
And while you have the wheels suspended, check the play in your bearings.

I'm not suggesting that it's a wheel bearing, but you can't rule it out yet, either. Once the car is in the air and the wheels are spinning, you can pinpoint the source of the noise.
I'm not sure how to do this with lifters, but try to get it jacked up in a way that you don't have the axles just hanging when the wheels are spinning. And don't run the wheels very fast when suspended, either.

if you're getting the humming in neutral..it probably is not the transmission.
at this point i'm going to say diff.
you still need to find out what the weight of the diff oil was used...in any event, i would put in le-607 right away.
