Rear pinion angle with lift installed.

I am probably way overthinking this stuff. I installed a Clayton 2.5" Overland + lift a couple of weeks ago. Jeep drives great so no issues there. I do need to add a little more front caster. Currently I am at 4.2 degrees left and 4.5 degrees right. That should be simple enough. Just shorten the front UCA's. Where I am all spun up is the rear driveline geometry. I have watched videos and they seem to address that with 1 piece driveshafts with cardan or u joints. Here is what I have currently and keep in mind that my driveway is not flat. The slope of the driveway adds like 2 - 3 degrees so I am really just looking at the difference between the angles.

Rear pinion is at approx 9 degrees, the driveshaft is approx 10.5 degrees, and the TC is at approx 10 degrees. I was under the impression that the rear pinion and driveshaft should have a difference of about 1-3 degrees.

I am not sure if this is a "the truck rides great so if it ain't broke don't fix it scenario" or if I should be trying to hit specific numbers. Do you guys see anything that is off and needs to be corrected or let it be?

I had a similar situation after doing the mopar 2" lift. I ultimately picked up some adjustable rear upper control arms to get it into that 1-3 degree range (I think I was 4-5 before). From what I understand, it won't affect your handling at all, it will just gradually chew up your u/cv joint...
