Just got done doing this myself 20 minutes ago.
1) Loosen the three mounts to the steering column, directly under the dash.
2) Remove the four bolts holding the column to the floor
3) Drive the roll pin out of the steering coupler
4) Pry the coupler off of the spline
a. You'll need to work this back and forth a bunch
b. Penetrating oil in the hole where the roll pin was helps
c. If it gets near the end of the spline, but doesn't quite come off, you'll need to
support the column and remove the 3 nuts under the dash
5) Remove the cotter pin and castellated nut from the pitman arm
6) Seperate the pitman arm from the draglink
7) Remove the three 12 point bolts holding the box to the k frame and don't drop it,
it's freakin heavy
Hope this helps
