Thrust Angle Off?

I have an AEV 2.5" lift with the geometry correction brackets and no other modifications to the lift. I also run 35" tires. I went and had an alignment done yesterday and the Thrust angle was .42* almost double the acceptable range.

I've got a17.5K miles on the jeep and it's shown no real handling symptoms. I assume I should look at the rear CA bushings first? What could have caused this to be out of spec?

Thanks!
Kelsey

I have had the same problem on a 13 rubicon. The only difference is I have a Tera Flex 3" and and a rear track bar relocation bracket. Mine was .37 deg off and my only worry is that they can't seem to get my steering wheel straight after my second alignment. Everything else was in spec. Is this thrust angle a simple cure. .37 deg in the distance of the axles can't be much. I hope someone steps in to help both of us.

Thrust angle is controlled by your rear CA's I believe. If the control arm bolts were not loosened, and any binding freed during install. This can alter the thrust angle.
Bent axle or Ca or like mentioned a bad bushing.
Lastly, The axle being off centered can slightly alter thrust angle. Not much but it will.
A track bar axle brackets main purpose is roll center. Depending on lift height, you may still need a adjustable track bar to center the axle.
