if it were a ProStar, or many other different makes and model of truck, I could tell you. Unfortunately, you picked one that I haven't ever had to make that repair to. So I'm making a call based on what an image result for "International 9400i cab airbag" turned up.First, you need that cab raised - ideally, somewhat higher than what the cab raises up to on its own. If there's a crossmember that'll allow you to raise it with a bottle jack, that's a good way to do it - use a piece of angle iron to distribute the weight if you have to push up on the exterior sheet metal at the rear of the cab, or a board if you're pushing up on the floor. Or, you can air it up. If you have one leaking cab air bag, you can pinch off the air line to it and let the other air bag do all the lifting, and you can adjust the ride height by manipulating the leveling valve, then you change one airbag at a time, pinching off the air line to each one you're changing as you change it.

From what the image result returned, the air lines connect at the bottom of the airbag. Disconnect them - it'll be a simple push in fitting - you push the air line and fitting in, and, while keeping the fitting pushed in, pull the air line out.

Now, that air bag will be secured somehow at the bottom... how, I don't know.. it might be bolts, in which case, you simply unbolt them. Or it might be a locking tab which you can pop off with a screwdriver. Or possibly a snap ring, which I recommend a set of snap ring pliers for. Once you have that disconnected, the airbag threads at the top into a stud protruding from the cab - simply unscrew it, screw the new one, and installation will be the opposite of removal.

There's no fun in playing it safe. Why not try something a little unhinged?
