I have read tons of threads on DW, most all theads seem to be dealing with spacers and lifts that have been put on the jeeps. On my 99 it's bone stock does this simplify the problem? Like balance, tires or is the track bar still likely?

Tires, alignment...what do your tie rod ends look like? Ball joints good? Could be any of the typical standard things that people with lifts deal with..even on your stock rig. My ball joints are shot and if I catch an abrupt non-perpendicular (meaning the front tires hit it at different times) bump, then I get a little wobble. And my rig is stock.

start simple first get your tires balanced, see if that fixes it, if not move onto an alignment, if your ball joints or tie rods are bad they will tell you cause they won't be able to align it, then get those fixed and finally if none of those help move onto the track bar, I learned this the hard way by spending money on parts that weren't needed on an 05 right hand drive tj, father in law is a mail carrier and we were driving his spare mail jeep for about a year.
