The leaf springs do a mediocre job of locating the axle, so many people ditch the track bars. By mediocre I mean the axle isn’t going anywhere, although keep in mind leaf springs are mounted to flexible bushings so at least on the front axle due to steering, there will be a small amount of slop. It’s tolerable to most but I added a front track bar back after years of not having one. The downside to a track bar on leaf springs is they are not forgiving when the track bar tries to swing the axle in an arc on suspension movement while the leaf springs only really want to go up and down. So you can add one back at your choosing. Don’t add one back to the rear. There is no purpose for it and no reason to have it.
The pitman arm is definitely stock looking at the height of that drag link. I don’t like that drag link angle. This is what makes the YJ steering suck. The drag Link is mounted to the tie rod. The drag link angle due to lift means when you go to steer, the tie rod will roll (pivoting on the balls of its two tie rod ends) until it reaches the limit of rolling. Then, the wheels will start to turn. When steering in the opposite direction, you’ll have to work through the same amount of slack until you reach the tie rod roll in the other direction. That creates a loose steering feel and is much exacerbated by a suspension lift. Highly recommend a drop pitman arm - it will still work fine when you ditch the shackles. A drop pitman will ONLY improve the steering, this is not like a TJ. If you do decide to add a front track bar back, and you do a pitman arm, then you’d want to get a track bar bracket as well so you can match the angle with the dropped pitman.
Very common for the sway bar link bushings to be dry rotted. My stock ones were dry rotted 10 years ago and probably way before that. I have always used stock length links, they’re decent. I’m using Skyjacker quick disconnects now I believe. Really what I’d like to do is get pics of a bone stock YJ and where it’s sway bar sits height wise and try to get links that put mine at the same angle. It’s been a while since I’ve seen a stock height YJ and it’s sway bar setup, so I forget what it looked like but it seems the skyjacker links I got have my sway bar sitting lower than it did from factory. Which I think is fine, but it’s always good to mimic stock design.
Many run without the sway bar also but I really don’t like the feel of that. Especially on OME springs, mine was scary to try. Not sure about others.
