If you send my your e-mail address I'll send some exploded drawings from the '78 FSM. They're too big to post.
To get it apart, you basically unbolt things, starting from the outboard end. There aren't any special tricks. After the spindle is off the axle shaft,the U-joint and stub axle will pull right out. There's a threaded hole in the end of the stub axle that you can screw a bolt into for a better grip.
To get the knuckle off, after removing the steering links, remove the lower ball joint nut and back off the upper nut flush with the top of the stud. That keeps the knuckle from falling when the tapered studs break loose. Then break the studs loose with a hammer. After they're loose, remove the upper nut and the split ring seat. You may need a special wrench for that, or you may be able to loosen it with a punch and hammer.
It'll make sense when you see the drawings.
