Stock transfer case angle?

[Xposure]

In stock configuration does the transfer case sit with any angle or is it perfectly horizontal with no downward angle? When I put the angle finder on the output shaft I’m getting about 8 degrees downward. My transfer case has about a 1” drop so it makes sense that it is sloping downhill. If I remove the tc drop should the angle go to 0 or close? If a motor mount spacer is added without a tc drop how much downward angle will that typically put the output shaft at?

I just got rear adjustable upper control arms and currently still have the slip yoke but planning to swap that out. Just looking at different alignment options ideas. I’d like to get rid of the tc drop, however more importantly to me is I’d like to get it vibration free, currently I’m having a little vibration when accelerating.

The angles you care about are the drive shaft relative to the t case output and relative to the pinion.

The angle of the t case relative to the frame is what it is, as a result of whatever you may need to do to get the other angles correct.

But the tcase output is based on the tcase in general....in theory in my mind (questionable I know lol) raising and lowering the tcase (with engine in same place) should change the angle of the output shaft, not just it's height. That's why I was wondering what the stock tcase angle is...so I can get an idea of how much the tcase drop is affecting the angle and how removing the drop will affect the angle.

Mine is 6.0 degrees downward, for whatever that's worth. I installed a new transmission mount, and I suspect the engine mounts are sagging.

I'm aware the pinion angle should be parallel with the TC output shaft in a perfect OE world. What is an acceptable range of angle disparity between the pinion and TC output shaft? Is there an ideal driveshaft angle range?
