Now, locate your torsion bar adjustment bolts. Locate the long bars protruding from the rear of the lower A-arms and follow it back to its mounting point on the frame. One of these bolts is underneath a skid plate that will have to be removed.
First, remove the skid plate bolts, then remove the torsion bar adjustment bolts. I have found that a 27mm socket fits best over these large bolts. They are fairly long, and it would take quite a while to remove manually. (without an air-ratchet)
Once you have the bolts out, push the torsion bar forward, to release it from the height control arm, remove this arm, then remove the torsion bar. Don't install the new torsion bars yet. The remaining empty bracket will look like the picture at top.
