Thanks guys. I just couldn't see opening the system and making such a big mess. I made a big enough one as it was.

Here's what I did.
1. loosened the steering shaft coupler at the sector.
2. removed the sway bar.
3. removed the front wheel.
4. took the pitman arm loose from the center link.
5. removed the plastic shield.
6. removed the 2 front bolts from the frame to the sector.
7. loosened the back bolt and let the sector pivot where I could get a puller on the arm and took off the nut. I had to slide a rubber sleeve up into the sector to get the puller on.
8. cranked on the puller until the arm came off and then put the new arm on and tightened to torque specs.
9. pivoted the sector back in place and torqued the bolts.
10. torqued the arm to center link bolt.
11. installed the sway bar.
12. installed the wheel and torqued the lug nuts.
13. torqued the steering shaft coupler bolt.
14. took it for a drive (couldn't leave it at 13 steps.)
