Wait, I confused us both by having incorrectly thinking you were talking about your rear pinion angle. I looked again and determined you were asking about your front axle. What I said was all true where the front axle is concerned since your front driveshaft has a DC joint.
But all this would be incorrect for the factory rear non-DC rear driveshaft, though it would be correct if the rear driveshaft has been upgraded to an aftermarket DC style driveshaft. What is installed in the rear? Is the stock driveshaft still there or has it been replaced with an aftermarket DC driveshaft. If your rear driveshaft is still stock then the angles I have described above would all be incorrect for the factory style non-DC rear driveshaft.
This drawing is correct for the standard non-DC rear OE driveshaft as the factory installed in the rear. Its pinion angle needs to be the same as the angle of the transfer case output shaft angle... aka parallel to.
