You dont pull the leaf. You undo the u bolts, put 2 c clamps on each side of the centering pin, Undo centering pin, Undo C clamps, put in AAL, Clamp back down with U bolts, Tighten centering pin, undo c clamps, reinstall U bolts. Thats it for the AAL.
You may need to unbolt the sway bar end links to get the axle to droop far enough to put in the new coils.
On the aal, make sure your c-clamps are pretty big so you can get it around everything once you have it undone. When it is together, it looks like all you need is a small c-clamp, but it opens up quite a bit as you undo the leafs.
Also, as you compress the springs back together, put a large screw driver, or something that is almost the exact same diameter as the center bolt (like your old center bolt) into the center bolt hole, inserting it from the top (so you can remove it later). This keeps you hole aligned nicely so when you're leafs are back together, your new center bolt can slide in easily from the bottom. Do not put the new center bolt in as you compress the leafs because if the leafs are not exactly aligned, you can easily strip the threads on the center bolt. Your new center bolt will probably be way too long, so after it is installed, you will want to cut off the excess.
Also, after you tighten up the u-bolts, make sure your u-bolt nuts have thread extending beyond the tips. If not, you will need to get longer u-bolts. Do not drive it if there is no threads sticking out, that is dangerous since they can work loose if the tips are not into thread.
Lastly, make sure you have a torque wrench. The u-bolts need to be torqued, as do the shock bolts. I can't remember the exact torque specs, but you can find that in a Chiltons or Haynes manual.
