Duster front ride height

Thanks for all of your replies. The front tires are probably too wide, but is a long story how I ended up with them. I completely understand the process of measuring drive line angles except that I was under the impression that raising the front would put more weight on the rear and as the axle goes up toward the body because of the increased weight, that may cause the drive shaft working angle to change and for the length to vary (need to be a bit shorter). As someone mentioned it would not change the pinion angle or the transmission output shaft angle.
Am I overthinking it? I just wanted some more opinions on the subject.
