Squeaky Shocks

My shocks are suddenly a bit squeaky. It could have always been squeaky and now that it's spring and the windows are down, I'm just hearing it now. But even when I jump on the tailgate the squeaking happens - like an old bed frame. (Insert "when your truck's a rockin" here)

Any suggestions, or is this too vague? I could post a video at some point.

Thanks for any and all suggestions.
This place is such a wealth of information.

Sand/dirt stuck in the leaf springs? This usually happens to me when I go offroading. Once it dries, the rear squeaks like crazy. When I get back and just flex out the rear one side at and time and spray out all the dirt with a hose. No more squeaks.

Of course, you could be having another problem.
