I have a 'cut and paste' for you from the install manual for my lift that I put on a few months back, I never had the issue, but I hope something in there helps...
Problem: You experience “High Speed Wobble” after hitting bump at 35-40mph.
Possible Solution: “Death wobble” is usually a combination of items and typically there is not one easy fix. We recommend you follow these steps when trying to identify source. Start by looking for any loose movement in the steering. Watch the tie-rod ends where they connect to the steering knuckle arms. Watch the drag link and the ends. Watch the track bar—it should remain tight without side to side movement when dry turning. Check to make sure your wheel bearing are in good condition by jacking up Jeep and grabbing top of the wheel and try to rock it back and forth. Make sure your tires are balanced—we recommend they be “road force” balanced. Is your front end in alignment? Lack of proper caster angles may be the problem. Last but not least is the steering stabilizer. A new stabilizer will not fix the problem, but a worn out one will make the situation worse. Most aftermarket stabilizers significantly dampen the movement that is the precursor to death wobble—control this and the severity is limited.
