Off Center Axles after lift

Okay so I've had my TJ for a couple of months now and it was already lifted 4" when I got it. It has the SYE and I had adjustable control arms put on it. I also have 35s and 15x10 wheels. I've had it regeared to 4.56 and thought it would be good to go but just noticed when I was changing out the fender flares last night that the front axle is off center and is shifted to the drivers side quite a bit. I've heard this is normal with the stock track bar and doesn't really cause a problem other than rubbing. I don't like it so am going to put on an adjustable track bar. I would just like to know if there is anything else I should do to the suspension in order to make it as functional as possible? Do I need to change the rear bars? What is back spacing on the wheels? How do I know if I need back spacing? Are there any other components I should replace. I've had the shocks changed as well. Do I need to change the stabilizer? Will I need to get if realigned after?

FIxed length track bars pull the axle over because the track bar is connected to the chassis on one end and to the axle on the other.

Like the angled diagonal line in the letter Z. When the upper horizontal line of the Z (the Jeep chassis) is lifted up by a suspension lift, the track bar (diagonal line) pulls the lower line (axle) over sideways. Installing an adjustable length track bar is the only fix for that issue.

Backspacing is the distance between the rear edge of the wheel and its mounting flange as is being measured below by the yellow tape measure The more backspacing a wheel has, the further into the wheelwell the wheel and tire is positioned. Factory wheels have a lot of backspacing to keep the wheels form sticking out too far. Aftermarket wheels generally have less backspacing so they protrude out further. I like to have as much backspacing as is possible without it causing the inside of my tires to rub on anything.

Thanks for the info Jerry. After I install a new track bar would I need to have an alignment done again?

You won't need a complete alignment. You would only need to re-center the steering wheel and set the toe-in which can be done in <30 minutes with just normal hand tools and a tape measure. Those are easy enough that you should just do them yourself. Like explained here... http://www.4x4xplor.com/alignment.html
