Thank you for posting those numbers (and crawling under there in the rain)!
I think I'm reading this right, but don't fully understand how you have some of these numbers. Are they the angle through
the ujoint or the angle of the part in relation to the ground? You have to subtract from one side of a ujoint to the other, to get that joints angle. It's not the actual tube angles that you want, in the end.
For example, tcase joint (which is hard because you have to get the angle finder on the tcase flange), measure the flange, then measure the forward shaft, and subtract to get the ujoint angle at the tcase. (So if your tcase flange is down at 6*, and the driveshaft is down at 10*, then the tcase angle is 4*).
Then for the center (the easiest angle to find), you measure the rear shaft and subtract the forward shaft from it. Finally for the pinion joint, measure the rear shaft and subtract the pinion flange angle.
Using that method, I think I'm somewhere around 4.5* downward at tcase, 3* downward at center, & 2* UP at the pinion joint.
Are you saying that the rear shaft is only at 8.5-9* and the pinion is actually steeper at 10*? That would put your pinion at say 1-1.5* degree DOWN instead of the usual upward angle there?
In relation to the ground, it sounds like you are saying the forward shaft is actually steeper than the rearward shaft... meaning... you dropped the carrier below
the point of a straight shot. Is that correct?
Sorry if I'm misunderstanding.
