rear hub nut
Got a F-250 2 wheel drive. I had both rear axle seals leaking...replaced them both and I snugged the nut down like you would do in the front...went to pick something up with the truck both axles were leaking and the truck was driving funny. Brought it home and tore back into it and both nuts had worked there way loose...what am I doing wrong here?

The rear hub uses a nut that takes a special socket. You can do it without the socket but it makes it harder to tell how tight the nut is. It sure sounds like it wasn't tight enough. I usually drop the bearings in gear oil to make sure that they have some lube to start with.

Here are the hub nuts.
Here's the procedure;
Install the hub nut on the spindle. Make sure that the nut tab is located in the keyway prior to thread engagement. Turn the hub nut onto the threads as far as you can by hand, noting the thread direction.
Install the hub wrench tool and tighten the nut to 55-65 ft. lbs. Rotate the hub occasionally during nut tightening.
Ratchet the nut back 5 teeth. Make sure that you hear 5 clicks!
Make sure the tang that fits in the keyway is not broke off. If it is, or your nut doesn't click when you back it off, then you will need new nuts. Autozone has them, part number 615-134. They come as a set of two for $80.

That's your problem. The whole thing is spinning without the little tab. Grab the od with your hand to hold it, and then take the socket and try to back off the center portion. It should try to stop you, or you should feel it clicking. Your whole nut is turning, there is nothing holding it without the keyway tab.

I got one at NAPA. They had it out on the floor, not even hidden in the back somewhere. Mine has "NAPA 3195" printed on it. It looks a lot like this one from NAPAs on-line catalog:
NAPA AUTO PARTS
Not sure if this is the correct one, but it really shouldn't be too hard to find.

I am sure it could break off, especially if someone didn't have the right socket, was tapping on it with a punch, and started hitting on the od of the nut instead of the id were the clicker thing is.

And to be complete, my Ford service manual gives the specs for installing the spindle nut on the full-floating rear axle as:
Tighten hub nut to 75-88 Nm (55-65 lb-ft). Rotate rear hub occasionally while tightening. Ratchet back eight teeth or notches (1/6 turn) on the hub nut.

Did you get to the specified 55 - 65 lb-ft of torque with your screwdriver and hammer? My point being that getting the correct tool not only makes it easier, but also allows you to do it right rather than probably good enough.
