I've got a 79 4x4 with a leaky steering gear box.
Schucks(
http://www.partsamerica.com) lists the seals I need. The Haynes manual has no pictures on the rebuild, and the pitman arm is "rust-welded" to the shaft. I've broken one standard puller trying to get it apart.
Questions:

What is a reasonable fee to have a shop replace the seals and/or rebuild the box?

Should I consider power steering out of a Trooper instead? I can get a pump, box, hoses and reservoir for around $150.

Should I only have the pitman arm pressed off and do it myself? I've done just about everything else on this truck imaginable.

Does anyone know where some good pictures are online?
