Could this be radial tire pull?
Put on my lift(see below) and then had an alignment done. The alignment was performed after winch and bumper were on. Everything was to spec, caster, toe, thrust angle etc. When I got home I noticed that after I added the bumpers and winch the body was no longer sitting perfectly over the axles, so OCD me realigned them. Now this should not change anything since neither axles left the ground, I just esentially rotated the body a little bit. Now I have a right pull? I am an idiot because it drove great before. I also have about 0.5 more castor on the right at this time. So what is the probability that I have to take it back to the alignment shop vs this being a radial tire pull?

If it was not pulling before you added your stuff and adjusting your alignment it probably is not tire pull. You probably took it out of alignment. You can always do what reneck suggested in my thread and switch your two front tires and see if it pulls in the opposing direction.

Quick questions:
1. How can the JK front axle have a difference in castor from one side of the axle to the other? The only way I can see it happening is if the axle was bent/twisted in service or made that way.
2. What was adjusted to "just esentially rotated the body a little bit"?

Ryanc,
No info on question 2?

I wish I could draw this. The body is connected to the axles, with the axles on the ground you can essentially rotate the body. Think of it of two rotating planes. I confirmed this with the alignment specs. The castor can be adjusted, but you have to remember the caster angle is not 2 dimensional, like when it is "estimated" with an angle finder, but is multidimensional due to SAI,

if the body is not sitting over the axle square after you added the bumper and winch then that means the weight lowered the jeep making the track bar move the axle over and making your alignment off . get another alignment go to a Firestone and get the life time alignment 180.00 never have to pay for it again
