Ok quick back story. Bought a 2010 jku with 3.5 pro comp lift. Factory control arms and no cam bolts. Decided to go with the rubicon express geometry correction brackets. I'm going to put them on tomorrow and I have been reading forums and watching YouTube all night trying to figure out what my caster is currently at. Right now I'm getting 88* on the front of the differential at the bolts to the right of the diff and 93* at the pinion. If I'm doing the math correctly that's 5* and my caster should already be almost perfect. I feel like I'm missing a step here and anybody that could explain it, I would really appreciate it. I can provide any further info you might need. Thanks in advance

 

The only accurate way to know your caster is to have it checked on an alignment rack.

Once you do that, you can keep track of how much you change it at home.

 

I'm following this. I have the same lift on my 2016 JKU. We installed Core 4x4 lower control arms on New Years Day. We took the stock arms and adjusted the new ones to an 1/2 inch longer then stock as the guys from recommended. I'm surprised how much better it rides. Doesn't ride so stiff. I have an appointment Tuesday for an alignment at 4 wheel parts.

Good luck with your Jeep 👍🍻
