Ok so I have a 2010 JKU that had a 3.5" Rough Country lift on it. I switched it out and added the Rock Krawler 3.5" mid arm , 3 link rear , tie rod and high steer drag link. I got an alignment. I'll post the alignment print out. But now all my abs and traction control lights are on. My steering wheel is straight. Any ideas where to start

 

I would check your abs sensor connections you might have pulled one out. if they are all good try disconnect your battery for a few minutes.

 

Ok I'll try that. The lights go on and off so maybe it's a sensor.

 

Agree sounds like a bad wire or sensor.

As far as the alignment
You have too much cross caster up front causing some bind. Shorten the upper or lengthen the lower a turn.

 

thanks I'll do that.. Guess I'll check the sensors on my next day off. I thought the caster might of been a little low. I thought I read most run around 4.5.. Is that right

 

Correct with about a .2 difference side to side (higher on the right)

 

Respectfully disagree. The cross caster is fine unless he notices it pull to one side.

That said, his caster is too low. Should be up around 5.

 

I had the same issues after a lift install, but they went away after driving it a short while. It may simply need to re-calibrate.

 

Mine with kick on and off.. Not sure where to start
