Stock TJ Caster Off

I had an alignment done on my 2003 TJ and they fixed the toe but not the caster. It still pulls to the right because of this. I am aware the caster is not adjustable with stock equipment and the shop said that as well. They said that they could try using shims or something to fix it. What I'm wondering is, how would the caster be off if it is not adjustable on a stock suspension? Would something have to be bent, or could it be ball joints? I have 15" Mickey Thompson wheels and 31" BF Goodrich tires.

If you have cam bolts in your front lower control arms then your castor is adjustable (which you shouldn't have with your year). If not, it should be in spec and fixed. If you don't have cam bolts and it's out of spec, chances are something is bent. However the castor wouldn't cause it to pull to one side, it would cause a light, flighty feeling.

If you have a lift and factory control arms your castor would also be off, but you would fix that with Adjustable Control Arms. Good Luck getting it all straightened out!

Caster angle is not independently adjustable for the left and right sides. And there is supposed to be a slight caster angle difference between the left and right sides, the knuckles were welded into position to give that slight caster angle difference.

Could a brake caliper be hanging up or possibly uneven tire wear or pressure between the left and right sides?

How bad is it pulling. Sometimes a sticking caliper can cause it. Also, radial tires can have tire pull that sometimes, simply swapping the front tires from left to right and vise versa will correct it. And of course, tire pressure can affect it also.
