Be warned!
The steering box is held by three bolts and it is customary for at least one to snap. This is usually the bottom one. There is also an aluminium spacer between the box and the frame rail and this can break up during the removal process (probably will).
These are dealer only parts and I dont recommend replacing the bolts with any old item you have lying around as it is kind of critical. Before starting the job it might be worth buying a couple of bolts and a spacer or at least making sure you can get hold of some in a hurry should the need arise.
