suspension lift and speed wobble

[Anker26]

I recently added a rough country 3" suspension lift to my 97 cherokee. Now when I reach 45 mph, the front end begins to shake violently. Speed wobble is how I can best describe it. Any ideas?

You probably need an alignment. Badly.

Or, your stock track bar is too short- pulling the front axle towards the driver's side. An adjustable one and alignment after would be great.

Its a pretty common problem, search the forum for "Death Wobble". Usually it is as Henry stated, the track bar is too short. Often a lift can exaggerate problems as well, like worn bushings or bad balljoints. Double check that every bolt you touched (or went anywhere near) during the lift is still tight as well, once the lift has a couple miles on it sometimes things can loosen up.
