First off, pardon my terminology if it’s incorrect. Still not entirely sure about everything lol.

What’s the difference between caster angle and pinion angle?

I just installed an Adams 1310 front driveshaft and was seeing that they wanted the pinion angle adjusted according to the image I attached below. The lift kit I had installed a few years ago did not come with adjustable control arms just fixed control arms so I was considering purchasing a set of adjustable UCAs, but before I do so I had a couple of questions.

1. Will installing adjustable UCA’s allow me to adjust pinion angle?

2. Do I need to have the axle at full droop to install the UCAs or can I just remove the old ones without lifting the Jeep and install the new ones adjusting the pinion angle by placing a jack underneath the pinion?

I haven’t measured the current pinion angle or caster angle or anything like that yet because I don’t know how to. Can someone please provide a diagram or images on how to do so?
THANKS!!!
