First off, you need to understand that your axle will always be a little off center depending on how many people you're carrying and/or how much gear you have in your Jeep. It's just the nature of the beast when it comes to solid axles with a track bar and really, it's not a big deal. Having said that, an adjustable track bar will allow you to get your axle more accurately centered at ride height but, depending on how much lift you have, the geometry of it can be quite off. For the amount of lift you have, I might recommend a reinforced relocation bracket on the axle end. That will help you to get your axle re-centered for the most part and correct it's geometry at the same time.
