ok so serviced the diffs and transfer case still got a whine....
good news is I found the issue with my vibration at takeoff its the trans mount didnt want to have something fall off while driving so took it to the shop and they showed me where its wore out. found a good write up on how to diy on the forum. so at least I can fix that

 

If it changes with steering (mostly) it's front axle related.

 

well it seems to do it only when really romping on the gas..i really hope no axle problems. I will fix the mount and update if it helps, in the meantime what would u suggest checking?
