Okay....dude. Everyone here is trying to help with some suggestions. The one I keep seeing and haven't seen you try because you keep justifying it is the air pressure. Try it! just lower them to 28-30lbs and see how it runs. If it changes nothing then air them back up. Just sayin...people are making suggestions, that is one that, unless I missed it, you haven't tried.
I agree with the OP that while 40 may be high, it should not cause "darting across lanes" unless something else is going on too. If going to lower pressure "fixes" this, it's surely a bandaid, kind of like throwing a steering stabilizer on.
Based on what you said, I think you need to find a new shop. Anyone who says you shouldn't have big tires on a JK is totally out of the loop. It looks like most dealers in Arizona have a couple JK's with 35's on the lot.
There must be a number of shops up there in Phoenix that practically do nothing but put lift kits on JK's 6 days a week. I'd try to find one to get some help. Good luck.

I'll agree with the post above... New shop is a must. I'm not sure how an alignment shop could tell you that an increase in positive caster (ie-new ca's) won't change your vehicles handling characteristics. Caster, camber, toe, & balancing is all these guys are supposed to do!! Sounds like a guy that can run the machines bit doesn't comprehend how the physics of angle adjustments actually work! You ever get that angle finder?

Go to the link above for your off center steering wheel fix. That's an easy 5 min fix. It also explains alignment on the JK.

Im taking it in to my dads shop Monday night. Going to put it on the rack and check every nut and bolt and see whats what. Thanks again guys for all of your support and ideas. We will find the problem and hope this might help the next jeeper if it every happens to them.

OK so went to my dad's shop and did some looking and everything seems fine. Put it on the alignment rack and did some adjustments. My caster is at 2.5 degrees and my dad thinks that might be the problem. So im going to order some lower front aca's and see how that helps. Does it matter if I get upper or lowers? Because one or the other should work right?

I'm not sure if this has been mentioned but soon after installing my lift kit i started to experience the DW's around 40-45mph.
after numerous times re-checking the torque and alignment nothing seemed to work. What ended up resolving the issue for me was new swawbar quick disconnects.. When i installed my lift I had also installed the tereflex quick disconnects, well after awhile i grew tired of the way they operated and purchased the JKS disco's. as soon as i replaced them and positioned the swaybar perfectly horizontal it went away.
For that reason if you do end up replacing them i highly recommend the JKS quick disconnects. you can easily adjust the length of those ones.
Just letting you know what ended up fixing my issues.

Even though either uppers or lowers can adjust castor, most choose to start with the front lowers. One, they are beefier than stock and will likely take the hits while wheeling. Two, the front uppers are a pita to install because the frame mount bolt has to be cut to be removed due to clearance issues. So if I were to choose, go lowers.

With only 2.5 castor you are guaranteed to have a brand new Jeep after CA's if you get that angle up to the 6-7 range. Spec on that is supposed to be 4 anyhow (factory setting)... And with the bigger tires it can still feel a little flighty at that.

this may have nothing to do with it, but my steering sensor went out and I never knew it - my dealer fixed it for me and the track of my Jeep improved a great deal. Mine did similar to what yours did... got in it one day and it felt scary loose and wondered way more then the day before but I couldn't find anything. It was like that for months. I chocked it up to tire wear and what not. After the dealer told me they fixed it - the drive home was back to normal with no "getting blown by the wind" feeling any more.
