How about ball joints? They take a lot of abuse, especially on lifted trucks. Sway bar links? Track bar bushings? There are so many places that can make noise on the front end. I don't know what size end links there are, but long enough to get the ends fairly horizontal should be ok. The sway bar is just connected to both sides of the axle - being raised would just bring the angle down creating force angles more towards the frame as opposed to directed against the opposite side of the axle.
