Does this steering geometry seem ok?

I bought this jeep lifted the way it is. I need a few guys inputs on is the geometry look ok? And also is this a drop pitman arm or regular?

And lastly my rear driveshaft angle, it seems odd, like the rear end needs pitched more towards tcase. I don't feel any vibration though.

On that type of rear driveshaft, the output of the t-case and the yoke on the axle should be parallel to each other, hard to tell from pics but it looks close. If it had a double cardan at the t-case (like your front driveshaft should) then you would want the rear diff to point directly at the output of the t-case.

Hard to tell if the pitman arm is a drop arm or not, looks like it could be but if it is there isn't a lot of drop in it. The angles look okay to me.

Angles look OK to my eye. That janky double stabilizer setup worries me more.

I thought it looked kind of odd to with two stabilizers that looks like some sort of welded up Fab I may end up trying to remove

My major concern is the double-stab may have been put in to cover up some death wobble, but I'm sure you'll find out whether that's true or not!

No death wobble but it does have some moderate bump steer...

It looks like you may have a drop pitman arm, that would cause some bumpsteer. Hard to tell without a good front picture that gets all four drag link and track bar mount points.

Ok I can supply that later. It's my understanding a drop pitman arm is needed over 4" to help bump steer?
Your saying it causes it?

Changing the position of the drag link mount without changing the position of the track bar mount will cause bumpsteer.

Over 4" you have poor angles with stock mount points, but you can still get acceptable steering with the stock pitman arm.

Alright. So I mount my track bar differently or get a stock pitman arm?
What is the best alternative for this to get all aligned perfectly?
Thank you.
