I am currently doing a 4 inch lift, and just bought a Currie steering system. I am planning on doing the alignment exactly like
@Jerry Bransford suggested, but I also purchased some toe plates from Longacre Racing, so when I am done, and it is back on its wheels, I am going to double check it, and see if anything changes. I am going to do it this weekend hopefully, so I will report back what I find. I am assuming as
@Jerry Bransford suggested it will be really really close unless I have a bad ball joint.
I will pull a myth busters on the TJ. haha
Personally I usually do mine as
@jjvw does with the weight of the Jeep on the floor on it's wheels.
