bump steer with drop pitman arm

I have on 07 f250 with a 4" rough country lift kit, after installing the kit my steering wheel was 180 degrees out. So my mechanic told me to put on a drop pitman arm on and now it has major bump steer. The other issue is that the front end either drops down when I turn the wheel to the right and lifts when turning left. What could be wrong? Excuse me for being a complete newb. Any and all advice welcome.

With that drop pitman arm you now need either an adjustable track bar or a track bar relocation bracket. The drag link and track bar need to be as close to parrallel with eachother as possible.

Do you still have the stock trackbar bracket on the truck?

First thanks for the qwik responses! Jakebrake, not sure as i didn't do the lift myself. I will ask my mechanic tomorrow. Excuse my ignorance, but what does this have to do with it?

The trac bar is the link that locates the front axle. It is the big bar going from thee pass. Side of the axle to the track bar bracket mounted to the frame on the driver side. The drag link is the bar in front of it that connects from the pitman arm to the knucle. These need to be pretty parralel or in phase with eachother to prevent bump steer. Based on the fact that you only stated that the pitman arm was replaced, seems to me the trac bar correction was left out. Take a quick look and you should see what im taking about. Hope this helps.

If your mechanic really new better and he installed your kit he should have recomended or made comment to the installation of the track bar bracket or adj bar.

Make sure you take the truck to a proffesional alignment shop when your done. That probably wouldn't be the guy that installed your lift.
