PUT THE CASTLE NUTS BACK ON A LITTLE LESS THAN HALFWAY; you want 3 or 4 threads locked in. If you put them on less than that, you risk the ball joint stud ripping through the nut and hurting someone. If you put them on more than that, you may be spinning the entire stud with the nut after it pops loose from the spindle, which makes it a pain to get the nut off. There are flat spots on the spindles; I don't know if they were designed that way, but that's where I whack 'em with a good size maul. The ball joint studs pop out, then you back the nut off and you're done.
Put a jack under the ctrl arms first thing. If you do it this way you won't hurt anyone and you won't be cussing yourself for not backing the nut off enough (yes, speaking from experience).
