Its an easy remove and replace if you are going like for like .
You need to get a pan and remove the low pressure hose from the metal line going into the box , its the one that uses hose clamps , and point that hose towards the pan . Let it drain as you go grab a beer .
With a line wrench ( I use a regular wrench , cheapy guy I am ) remove the hoses from the top of the box . You will only reuse the small section of hard line from the low pressure side .
You may need to remove the pump if you have no room to work , to remove the high pressure hose end behind the pump .
Now box removal is easy . Just remove the bolt that holds the pitman arm on , and drop the pitman arm . That way you don't have to play with rod ends ( assuming they are good anyways ) . Undo the bolts on the sterring ragjoint/coupler . If you are smart , you can leave the steering shaft where it is , undo the bolts that hold the box on , and drop the box away from the steering shaft without loosening anything on your steering shaft .
Now to put it back together , put new ragjoint on the new box ( larescorp.com makes nice steel belted ones ) and tighten retaining bolt . Put a pice of tape on the output shaft and turn ragjoint and count the turns of the output shaft , find what seems like the center , and leave it there so the pitman arm can go back on later and steering wheel should be where ya left it . Now set box down . Grab a beer . Put pressure hose on pump , and new loe pressure hose on pump ( cut to same length as old , or add some to route your way ) . Put box back up and into the steering column shaft , having helper helps . Tighten all bolts . Install hoses . Grab abeer and then come back and double check all bolts and hoses . Add fluid , start and turn box lock to lock while stationary , add more fluid as it just got sucked in to box , turn lock to lock again , check fluid level .
If it feels tight while driving , there is air left in there . Go park and work that thing lock to lock until its gone and shes smooth as butter .
