Best place to start is to get an alignment after you install your lift.
Then Check your Track bar to make sure it is snug and not wallowing out the hole.
If that doesnt solve your problem, thouroghly inspect ALL of the rubber bushings up front (including CA bushings), ALL of the ball joints, if a boot is torn suspect a bad BJ. Remove the tie rod ends one at a time to see if they are worn....
Then go through and retourque everything to factory specs.
Do a few searches, there are a lot of threads on this topic... but those listed above would be a good place to start. Good luck and let us know what you find.
