2.2 Degrees of caster? Seems a little low to me, I believe the low end of the range is 3.5, Im running mine at about 4.2 degrees

But lets say in a perfext world everything checks out track bar is right, ball joints bearings etc.. could the issue be something as simple as a castor tweak and rebalancing tires.

It could be something as simple as too much pressure in the tires. I can't count the times that people have complained of DW, wandering, bumpsteer, shimmies, wobbles, etc etc etc. and it all came down to 40-60 psi in the tires. Because they trusted the "tire guy" who put 50 psi in the tire to set the bead and didn't bother to bring it back down to 26-28psi. The Jeep especially the 2dr is not heavy enough to run those kind of pressures.

I think it's like 38 check your door jamb sticker.

Better check your door jam for tire specs.. My Unlimited says 35psi for the factory 255/75-18. As you increase tire size you reduce the pressure dependent on load rating..

If it dips below 45 my tire pressure sensors go off

Maybe your tire gauge is out of calibration.

Possibly. But I know for sure it isn't the cause for my DW.

You are correct not the cause, however, at this point it could very well be what initiates the DW.. Many things can initiate DW but the cause to allow DW to happen is usually some worn parts some where.
As for your TPMS have your dealer adjust it properly to what it is suppose to be 32psi min - 37psi max.

Just for laughs drop the pressure to 32psi and drive a bit, see how it feels.

I can't drive it anymore I cut the draglink out of it cause the TRE on the knuckle looked bad.

I had DW too the other day, turns out to be bad tires (wranglers). They balanced fine but under load they were out of round. At work we have a balance machine that also checks the road force so I fugured we check the newer dura-trax tires, one was slightly out of round so I put that one in the back. So I would suggest after getting your jeep back on the road swap rims and tires with someone that doesn't have DW and go for a spin. My front end guy has 30 years experience he did the alignment and took it out on the road and when he came back he said "get those tires off that jeep!" installed different ones, problem solved. I can still feel a slight wobble when I hit a weird bump on the road but it just goes away now instead of continuing on. Set my pressure @35psi.

If you're still getting tire kick and extra wobble when you hit a bump, that DW is probably going to come back unless you find the cause.

I agree. The DW is still in there. The tires were a trigger for DW.
