Therefore, I do not see how placing it on stands is going to magically recreate the noise, when it's clearly coming from the wheels.
The error is likely due to a faulty wheel bearing or a maintenance induced failure when replacing the wheel bearings improperly.

I wish it was wheel bearing. One if the first things I changed out because of the noise, found absolutely nothing wrong with the old ones, changed them anyway, SKF cups and cones. When the grinding started, I rechecked for excessive endplay (still set properly) and they rotated nicely. Have access to an on vehicle tire balancer for heavy trucks (spins up the wheels on chassis) going to spin up the front wheels and see what happens. Gave the bearings the ol' heat test too, all similar temp.
Placing it on stands and running it up would help show if it was from the trans or some strange harmonic showing up in the front, caused by the back? Just willing to try anything at this point. I went looking at a parts car for major component swaps if it comes to it.
