    ok, im about to change out my seal, but how do i brace the yoke to take the nut off? i locked the hubs, but i dont want to put that pressure on the gears.

    I use a large pipe wrench. Just let it rest os the spring pack and crank away.
    Be sure to measure your preload first so you know where to set it during reinstall

    that supports the yoke from moving? im not getting what you mean. i just want to support the yoke so i dont bust anything by putting to much pressure on it.

    I don't think you can damage the gears like that , there is no way you can put more pressure than driving it??
    I have done it this way a few times with no negative results.

    Multiply your engine torque output by your 1st gear and low range. That is the kind of torque the gears see under normal usage. You would need about a 50ft pipe to apply that same kind of torque.

    What I do is put a pipe wrench on the yoke and let it hit against the floor or the spring while wailing on the nut with a big breaker bar.

    ok, i got it off, thanks guys.

    now the new pinion seal has the exact same numbers as the old one, but they look a little different. does this matter, or are different manufacturers have different looks

    It's going to take an impact wrench that can put out ~300ft-lbs of torque. Be sure and mark the nut location with a punch so you can get it back on to the same amount of preload.

    I just hold it with my hand, take it off, put it on, crush the sleeve, everything.

    For reference, sometimes seal manufacturers will move the seal mating surface so that way the seal rubs in a new spot on the metal instead of the same old grooves.
