Gonzo,
You need to do an alignment after the lift is installed. How old is your truck? Everything should be in good condtion if it is fairly new. Once you lift your truck, then you need to start checking those components more often. If anything, get your brake lines replaced, when you get your lift, with steel-braided brake lines and maybe have your wheel bearings repacked with grease, since the are accessible anyways...Good Luck! <IMG SRC="/board/images/smilies/bigthumbup.gif">
