I just got doing this today and the original reason was a torn boot, however, I think I am going to do the other side as well. It is amazing how much new grease goes in from the kit vs what I took out (which wasn't much). I'm sure these were never done before. Job wasn't too bad. Made one mistake and it got real messy. Anyway, here are some pics:
