Honestly, you do not have Coils nor a Spring over, the only reason for a Jeep to have a track bar in the rear is to control to things,
1: Wheel Hop, you do not have a Sports car
this reason is Useless
2: Spring wrap, if you have a problem keeping off on the gas more than you need to then you need it for this reason.
I have taken both my front and rear track bars, they limit travel offroad but make the on road driveability much better, it is really choice for you. taking them out will cause your jeep not to feel so much like a Corvette on the road. I found them absolutely Useless so I took them out along with the Sway Bars, Mine drives just fine.
at any rate take it out for now until you decide to either fix it or keep it out.
