Please don't give incorrect advice.
OP: You should start with a dry steering test to identify any loose or worn components in the front end. To do this, put the key in the ignition and turn it to the first click "ACC". Have someone turn the steering wheel side to side while you look under the front, if you take a video it might be easier to help you out.
Also, check the bushing and nut on the trackbar at the axle end, then check the bolts holding the trackbar bracket at the frame side. There should be no play and the bushing needs to be in good shape. If it is loose, check to make sure the bolt hole is not wallowed out.
What does your lift consist of? If you did not replace the control arms, are the bushings in good shape? Is it possible to move the arms by trying to shake them?
