The box and column are 1 peice. It's not really too hard to remove, but it can be a bit awkward. The one thing that helps the most with taking it out will be to remve the drivers side fender and inner skirt. This will allow for the much needed clearance. Tp remove the box, remove the pitman arm, the steering wheel, column shifter and trun signal controls (if equipped), column drop bracket under the dash, and the 3 bolts mounting the box to the frame. The column will have to be tilted down to allow it to slide out of the cab (this is where having the fender off come in), then once clear, the whole assembly should come out over the frame rail.
BTW, the second bearing you mentioed earlier rides on the top of the worm gear, the gear/steering shaft (again, 1 peice) has to come out to get to it.
