Torsion bar installation

The upper and the lower control arms should be attached the spindle. Remove the upper control arm bump stop so the suspension is at full drop. Then install the torsion bars.

Did you replace any of the control arm bushings during this process? If so you will want to leave cam bolts and pivot shaft loose and tighten them once the torsion bars are installed and the full wait of the vehicle is on suspension with ride height adjusted.
