Re: lift wheel alignment needed?
I have to support AZ Outlaw here... I have put several lifts on JKs, and I do my own alignments. I often do go to have it put on a rack to get a print out, as a frame of reference, and to make adjustments myself.
The ONLY alignment adjustments that can be made on a JK are the toe and the caster. Toe will NOT change, except for the slight impact as a result of the caster changing a little (without control arms obviously). At 2.5" it is not enough to change the to to be out of spec. Even so, it can easily be done at home with a tape measure and a couple of small turns on the tie rod.
Yes, the caster would change. Although, at that small of a lift, you likely would not get new control arms to adjust it anyway. It is also true that the "target spec" could ultimately change as to what you want your caster to be. OEM is 4.7* and with a lift and OEM driveshaft, you can run upwards of 5.5* and improve your ride and the return to center of your steering wheel. If you go to an aftermarket double carden shaft, you will likely have to run UNDER OEM specs to avoid driveline vibes.
Again, all that is kinda moot... with a 2.5" budget boost you do NOT need to get an alignment...
Edit to elaborate: If you choose to go over about 3" then you cross that line of what you need to, and what you should do. At that point, I highly suggest at least lower front CA's and rolling back your caster to improve your steering/handling. I also would NOT use a shop that is telling you that you HAVE to get an alignment after lifting your JK 2.5" or less... They either dont know what they are talking about, or are trying to take advantage of you.
