Well, if it's not the track bar , that's just take metal rod..it's the bushings or the bolt ,if it is the track bar .
The bolt can be badly worn, poorly torqued , and the bushings can fool you .
Normally on a stock jeep with fairly stock tires you don't get accelerated steering component wear , but eventually you do with anything.. eventually.
Remember you have 2 things- what causes it , or sets it off, in your case a surge , and what allows it , worn components.
I still think a wheel is acting up, you can even have a broke belt .
If everything is pretty tight...pitman arm , drag link ends , tie rod ends, track bar (and that's pretty much the entire linkage) a tire is the dominant issue ..put your back tires on the front and front on the back and see what happens.
