Why would the toe increase?

Btw, my friend just put a 2.5 Teraflex lift on and his steering wheel looks centered and drives fine.. Is that weird?

 

It should not change your toe or camber. I will change caster very little. I did not need to center the steering wheel on mine.

 

just recenter the steering wheel and your good. I had a leveling kit and had no issues with caster or anything.

I currently have 3.25" of lift up front and still haven't had a professional alignment. Jeep is getting smarter and making it possible to correct everything yourself with some patience and some know-how .
