how to replace steering box on a 2000 fl80

i need to replace the steering box. have lots of play in output shaft. i knoe i need to unbolt it. remove the pitmarn arm steering yoke and lines.

anything special i need to do when installing the new one?

is the input and output shafts keyd?

thanks

 

ok so i just got to make sure i get the steering wheel lined up.

do i need to raise the front axle off the ground at all?

 

so i installed the gear box. the steering wheel moves nicley in one direction snf very stifff in the other. is it just air do i just keep working it back and forth or what do i do?

 

also the steering wheel isnt lined up so im assuming i didnt get the pitman arm on the output shaft properly. there is a line through the output shaft. does that line up with a mark on the pitman arm? i didnt see one. i just tried to line it up compared to the old one
