Thrust angle is controlled by your rear CA's I believe. If the control arm bolts were not loosened, and any binding freed during install. This can alter the thrust angle.
Bent axle or Ca or like mentioned a bad bushing.
Lastly, The axle being off centered can slightly alter thrust angle. Not much but it will.
A track bar axle brackets main purpose is roll center. Depending on lift height, you may still need a adjustable track bar to center the axle.
