Rear Uppers are commonly used to raise the pinion to correct pinion angle. Youll see people will install front lowers for caster and rear uppers for pinion only. Rear lowers add wheelbase and front uppers are kinda a waste in a short arm setup.

Who you calling a loser? Lol Correct, decide and set your wheelbase with lowers. I prefer to install the lowers, ensure axles are parallel and square, then hold pinion angle where you want it and adjust the uppers to the mount locations. Torque before dropping the jack. Front you can do easily with the tires on the ground. Rear will need to be on stands with tires removed to gain access to the uppers. The lowers locate the axles so the settings of each arm are more important. Uppers lengths dont matter as much, setting to the mounts so all 4 bolts slide in/out ensures theres no binding or preload.
Also, are you suggesting the control arm bolts be torqued while still up on the jack? Don't people always preach to leave them loose, drop the jack, shake the jeep a bit, and then torque- in order to avoid binding/preload on the bushings?

I was so confused until I re-read my previous reply. I meant to say *lowers*, lol. Also, are you suggesting the control arm bolts be torqued while still up on the jack?

Also tightening at ride height mainly refers to the stock bushings or any arm with bonded rubber joints. Heims, Spherical joints wont matter as much as far as binding because the ball spins.

gotcha right now I'm at 1.3 driver and .9 passenger on camber will be doing my ball joints this weekend. Hopefully it is just ball joints not the c's if it is the c's I heard there's this wedge people can install to fix the camber issue, but pretty sure it's my ball joints that are bad.

I figured I resurrect an old thread due to having to tighten my LCA jam nuts.
I didn't have a Crows foot but I found a very similar method that worked for me.
Bench vise + C-Clamp
Then tightened down with a pipe wrench with a long pipe from my floor jack.

Metal cloak has these nice crows foot wrenches in 1 1/2" and 1 7/8" . We have them in the shop I help at and they are handy and the price is pretty good. They allow you to get into tight spaces where you might not be able to get a big wrench into.
