Squaring axles with frame

Does anyone know anythin about squareing the axles with the frame. I have changed to an sye conversion from tom woods and installed adjustable control armes on rear. {top and bottom} everything seemed good but something seemed a little wobbly if this makes sense. I measured center to center of each wheel and the left side was 1/2" wider than the right. Moved rear axle on right rear out 1/2" and seemed better. How would i need to square this up. I am going to take to alignment shop thursday but if it is something i have done i want to fix it.

I could be wrong but I think that is what an adjustable track bar is for. I have the same issue after lifting mine. Im about 1.5" to the driver side up front and 1" to the pass side in the rear. So to sum it up they are on my wish list.

Squaring the axle to the frame isn't as important as squaring the 2 axles to each other and getting the rear in line with the front.

Measure front to rear axles on each side to get them parallel - arm adjustments.
Then measure from front to rear in an "X", picking identical spots on both axles. Both legs of the "X" should be the same, 1/8" difference is acceptable - trackbar adjustements. This gets the front and rear tracking with each other.

The reason it feels squirelly is they are not parallel or are offset from one another.

After that's right, then step back and look how the body/frame sits on it. If the frame is not bent and is square - it'll sit fine.

You've probably seen a car that looks like it's going sideways down the road - called Doglegging.
That's usually caused by the axles not being parallel.

Good alignment equipment can measure that - Offset and Thrust Angle. Unfortunately most "alignment guys" don't know what it is or how to correct it.

Do a little searching on the internet for those names - there's lots of diagrams that show you what it is.

Whenever you lift the TJ, it shifts the axles out...I think the front goes one way and the rear goes the other. So you'll need to pick up an adjustable front trackbar and either a relocation bracket or an adjustable rear trackbar. I've never done the adjustment, but I'd imagine from there, you'd follow rrich's advice and it'll get you all lined back up. ...and had I read more, basically I'm seconding what JP was saying.
