[68 C10 LSX]

Used to post here under "My New 72" more than a few years ago but haven't been on in a while. The truck was in storage for 6 years and I just got it out to and on the road again. When I parked it, everything was good. It rode and drove great. The issue I am having now is, when I turn the wheels either direction to turn, there is a pretty harsh grinding going on. Everything feels tight, but its rubbing somewhere and I can't readily see where it's coming from. Any suggestions on where to start? The front shocks are tired and need replaced, but I wouldn't think that would cause anything like this. Thanks for the help.
