If you lower the jack the spring COULD come flying out. WITH THE JACK IN PLACE...... If you have a pickle fork use that to split the spindle from the ball joint. If you don't, usually a couple of good whacks with a BFH will pop it loose. As long as you're replacing the spindle anyway, it doesn't really matter. Just give the spindle a good pop right next to the ball joint. Do the same on the bottom ball joint when you get the spring out. Before lowing the jack, put a jack stand under the frame so the whole truck doesn't come down.
