    nope
    well it is simple but you neet to reset the pinion bearing preload
    to do it right you need a new pinion nut, and a new crush sleeve.
    the eaisest way to do it, unless you have all the tools, is to take the center chunk out and take it to a gear shop, just be careful to not loose the shims on the center chunk.

    In between the pinion housing and the axle housing to set pinion depth.

    right, It sounded like he was talking about shims for the carrier.

    oh nevermind it makes sense after re-reading it.

    To do it right you need a new crush sleeve and a pinion nut but I imagine you can probably get away with the same crush sleeve thats in there. I would check the pinion bearing preload on the pinion assembly (make sure to do this while the pinion assembly is out of the housing). Then put on the new yoke with a new nut and make sure you have the same preload as before. You will need a dial type inch pound torque wrench. Atleast that would save the hassle of pressing out the bearing and putting on a crush sleeve and recrushing it. But if I was doing it, I would recommend doing it the right way. Which will require a press to press on the old bearing back onto the pinion. I personally like to start the crush sleeve with the press then tighten it up to spec with a big breaker bar. If none of this makes sense maybe you should just take it to a good gear shop and let them do it right. Those pinions spin terribly fast and if the bearing preload is too loose or tight you will have big problems on your hands.
