It is worth mentioning that a wheel and tire balance does not check for wheel tracking - if your wheel is bent but balanced the machine will pass it, but you will have vibration. When balancing the wheel you have to verify the tire tread tracks true - if the tire track is not true the wheel itself is bent but the tire will be balanced on the machine just fine.
Held a straight edge to the inside barrel of the wheels, while spinning, all looked good.

removed and inspected:
-rear axles, roller sleaves, wheel bearings, diff.
Everything looked perfect, good, and not bent
Ring and pinion backlash was with-in spec
no metal flakes or debris.
Today i spoke with Jim at Strange Eng, today. He was extremely helpful.
His thought is the preload in the diff. (eaton truetrac) is out of whack or worn from not being set properly.
So now I pull the diff, "USPS if it fits it ships" and ship it to strange.
His reasoning for this, is because if I tap the brakes the vibration goes away This means the brakes equalize the issue inside the diff.
Plus this will give them a chance to inspect why the diff has howled/whined since day one. I have a few other friends with the same rear set up, and its quiet.

even though Strange is willing to assist with this.
I will be contacting EATON first before I send the TrueTrac to Strange.
I would like Eatons opinion first. Sadly their tech support guys were out of the office on holiday.
To bad I can not chalk this up as new DRs being out of round and throw on a new set.
Tires would be my conclusion if the vibration didnt go away when tapping the brakes.

I've been having a similar issue, I haven't tracked it to my axle but I think my car does the same as yours- when I hit the brakes at higher speeds the vibes will die down.
However I'm getting a light grinding noise at very low speeds, I need to go through all the possible culprits before blaming the newish strange 12 bolt though.
I just bought the car a month ago, and I'm already
about going through the entire car trying to track this down.

I still have not sent my diff back to strange or eaton, as I'm still not sold on the idea the diff has issues. Those things are bullet proof at my RWHP
Have you put the car on stands and ran it up to see if it still shakes? That eliminates the tires being out of round...you can pull the wheels all together and get it down to ds and rear...or the tranny. I'd be thinking tranny at this point.
