Does your steering get messed up when you lift your Jeep? If so, what happens and what does it take to correct it?

Yes. The angles increase. The simple way you correct it is with a dropped pitman arm.

When you do bigger lifts like SOA and soa with lifted sprigns, the way you fix it is crossover steering (so the tierod is above the springs instead of below, thus reducing your draglink angle). Basically, you want to fix it so the draglink angle remains as close to the stock angles as possible. If you don't, you get what's called bumpsteer. This is where when you hit a bump, your steering wheel turns. When it gets to the point where you get unwanted lane changes, it's time to fix it


FWIW, i have an SOA and a 4" dropped pitman arm, and my bumpsteer isn't bad at all. I attribute that to a wider front axle, which makes my draglink angle less than what it would be on a narrower axles with similar lift.

Greg, one correction: cross-over steering refers to the drag link going from one end of the axle to the other, just like stock Jeeps do. The terminology is frequently used by Toyota guys whose drag link runs fore aft on the driver's side (thus, any lift results in a greater angle than our cross-over steering setups).

What you're referring to is generally call a hi-steer conversion because steering arms are usually mounted to the top of the knuckle, or the tie rod/drag link is flipped and mounted to the top of the existing steering arms.
