To remove the whole assembly. First of all hold wheels in straight line, mark arm lever on housing at angle. There are 4 bolts and one driver side steering linkage. pull cotter pin out of linkage attached to steering box arm. use largest flat head screw driver availble and unscrew linkage knuckle from ball. Kinda like a hip joint, once loose enough it will pop off. 3/4 inch six sided wrenches and sockets are you best choice. remove two from side of frame using inside of frame as wrench holder. Renove top bolt using side of frame as holder of wrench. last bolt is underneath front of steering box I used 6 sided wrench and prybar to break loose then ratchet. After that pull whole assembly out and whalla.
