After what I thought was a simple hassle free 2" BB I noticed both axles shifting 1" in both directions, 2" in total travel. They may shift to the same side, or opposite of each other.
I'm reading adjustable track bars or track bar relocation brackets might be the fix. Yet concensus says 2" shouldn't cause that much travel, I also haven't caught any posts saying their axles seem to float independantly side-to-side as they please.
The jeep travels straight, no vibrations, nothing out of the ordinary. A shop is putting it on the lift tomorrow, alignment is next week.
What is popular opinion for a fix in the front? Back?
Adjustable track bar? Track bar relocation bracket? Both?
Finally, what damage or mechanical wear am I causing while driving until fixed? Tire wear?
Edit: There is no noticable play with the front track bar bushing. Definitely not 2" worth.
Agreed, a 2" suspension lift doesn't offset the tires (axles) enough to worry about. Definitely do your own toe-in and steering wheel centering which is easier to do than installing a 2" suspension lift is. And done with a modicum of care, your toe-in and steering wheel centering will be just as accurately set as the fanciest laser-driven alignment rack can produce. Literally and absolutely no exaggeration.

The axles are going to shift side to side as the suspension moves up and down. Take a look at the geometry. It is a Z. The top horizontal is the frame, the bottom is the axle and the diagonal is the track bar. The track bar length stays the same. Move the axle up and it moves to the left. Move it down and it moves to the right.

Go out to your Jeep and look at the axles so that instead of just believing what we're trying to tell you, you see and understand it for yourself. Comprehension is everything when it comes to understanding realistically-simple stuff like this. Start up front--the track bar mounts to the frame on the driver's side and to the axle on the passenger side. What happens when the vertical distance between those mounts changes? The horizontal distance becomes less, simple geometry. The axle "swings" through the arc of the track bar, so it will swing a bit over toward the frame-mount. The rear axle does the exact same thing, only the frame and axle mounts are reversed. Just by looking at the axles, it should be very clear to you what defines the location of them. The axles move through the arcs of the control arms fore-and-aft and move through the lateral arc of the track bars.
