more confused on how a shop didn't know that certain tire size won't fit depending on lifts, much less that they shouldn't be centered for an offroading vehicle. Or why you think installing a 3.5" IRO lift was a bad idea or "against your judgement" but hey, he paid you not us.
But yea, stickied and the track bar was the right call for centering the axle left to right, but CA's would be what needs to push the axle back, but that's not the issue here. Trim the fenders is the best solution IMO.
