Replacing Front half shafts

I have a 2001 Blazer LT 4 x 4 with 170,xxx miles. I'm looking to replace the front half shafts. Is there a write up anywhere I can refer to for a bot of help?

If the ball joints have not been replaced yet, they're overdue, and that would be an ideal time to do both jobs. There is a thread in the "How-To" section, with pictures!
