front end noise on 1992 Chevrolet S10 Blazer

What does it mean when I experience a slight but sudden "shift" in my S10 front end followed by a loud "clunk"?

It means something in the suspension is loose and needs to be checked out. Get a thorough inspection of the steering and suspension system soon, as it may be dangerous if it gets worse.
