I installed a 2.5 BB lift from teraflex looks great affordable the put on 18 in xd -12 offset and 33s goodyear duraTrac love the set up looks great but after doing all this I got a alignment done and put on a terflex steering stabilizer thinking this would stop the jeep from wondering on the road it doesn't pull left or right but when you get going about 45 to 75 mph it just wonders around doesn't drive down the road like I would like it too anyone have any ideas or some issues or I'm I just screwed

 

Check your air pressure, they usually over do it
29 to 32psi is good for the weight of a jeep

 

Also the alignment on that particular lift is just re centering the steering wheel.

 

A suspension lift tilts the front axle housing - raising the pinion - and lowering the caster. Low caster causes flightier steering.

Open the FAQ's and scroll down to the Suspension section. You will see one with a title something like "What is Caster? How much do I need?". That caster blurb will tell you what the stock caster is, your alignment sheet will show what you are currently at.

With 'stock' components, the caster and camber can not be adjusted, and the axles can not be re-centered. The Toe can be adjusted, but probably did not need to be. So it is likely that you paid the big alignment charge just to have them recenter the steering wheel.
