whining noise still there

whining noise on accelaration after about 30 mph. goes away when i let off the gas. i have replaced...

front pinion bearings and seal (with reciepts)
spider gears
both front wheel bearing/hubs
both cv axles
rebuilt my driveshaft (double cardan cv ball)
changed fluids in t-case and front diff

currently my driveshaft is out and there are no noises what so ever!!!
when the d-shaft is in, is when it whines.
any help at all?????? any opinions?
coming from the front/under the driver seat

I swapped out my entire carrier for another out of another jeep to see if it made a difference and it didn't. I know your not supposed to but the noise never changed. I have my original back in now.

What's weird about the noise is it goes away for a split second when I hit dips in the highway and the jeep bounces. The noise changes with compression and decompression of the springs. Maybe front output on t case????

Did you ever figure this out? It is exactly the problem I am having.
