93 Suburban front end noise

I have a 93 suburban 4x4 with the 454, heavy brakeing system with hydro boost ABS system. It has started making a noise from the front drivers side, I thought maybe the shock had froze up so I pulled it and the noise is still their when I bounce the truck up and down from that side. When I had the wheel off I didnt see any unusual wear on the joints. I dont know whats makeing this noise but it's driving me nuts. The steering feels good I dont have any unusal feelings driving it just the noise.
