    Go buy/rent the axle nut tool for your type of nuts.

    There will also be some sort of locking mechanism on the nut.

    E-brake off and front tires blocked front and rear.

    Go to Napa and get the socket, KD #2770.
    While you are there get a manual. The Haynes I have explains what to do to remove the hub assy pretty good.
    There are 2 different types of nut and lock nut assy's.
    Dana manufacture and Chevrolet manufacture. Both are a 14 bolt.
    My 73 has the GM style nuts, The K5 has the Dana style which I have never ran across before.
    I dunno what the Burb has I have not tore it down yet.
    Anyway once the nut or nuts are off pull the drum/hub assy straight off. be sure to back off the brakes. the 73 has the adjusting hole in the backing plate.
    The one in the K5 has them on the front of the drum, which I had to knock out with a chisle on one and drilll a hole and hog it out with a carbide bit on the other.
    You will also need a torque wrench to reassemble the hub to preload the bearings.
    Unless you know what 50 ftlbs feels like.
    I have prolly done thousands of hubs both light duty and ones on semis and I always use a torque wrench.
    Too loose and the seal will leak and eat bearings, too tight and well... that aint good either.
    There is one other type of FF, this one the drum can be removed by removing the countersunk screws. Never seen that critter either.

    Don't get the Chilton book. It doesn't even talk about FF axles. Once you get the hub/drum assembly off you'll have to press the lug studs out to remove the drum.
