The track bar relocation bracket will allow the axle to center itself back up under the TJ once you unbolt the trackbar from its mount. The track bar is under a bit of tension at this time but it's not enough to make the job difficult or dangerous at all.
The front could use the same type of help but there is no equivilent track bar relocation bracket available for the front. Instead, an adjustable length track bar is used to get the front axle centered back up underneath the TJ.
And a big welcome to WF vonHammer!
