Do you have a lift kit on you Jeep? With an adj track bar sounds like you do...and yes, if you put the stock back on, then the steering wheel and hence your ETC would be out of adjustment....and none of this has anything to do with brakes as far as I see it.
Sounds like you had bump steer, not death wobble...Which would be the drag link not parallel to the track bar. Did someone in the past play with the steering? ie. drop pitman arm?

I do not consider myself a smartass. I point out the obvious, search for the truth, and speak fluent sarcasm. I am, by experience, an accomplished curmudgeon.
