remove the tension on torsion bars

You back them out counter clockwise. Should be a 3/4 socket. Then if you are removing the bars and or control arms you will also need to remove the clips in the cross member behind the bars and the 15/16 nut on the control arm shaft, 3/4 nut on the strut rod where it goes through the control arm.... The nuts on the strut rod where it goes through the K member are 1" or 1 1/16 I think... Do them first if removing the strut rods but make sure you remove the roll pins first.
