Welcome to the DOC :!:
If your shocks are fine, then the squeaks are all most certainly coming from the front sway bar. The bushings there are terrible for getting the squeaks. I could hear mine squealing just getting in and out of the truck.
Do a search on sway or swaybars and review posts from the last 6 months. Plenty of great ideas and homemade solutions to the problem (motorcycle chain wax is a fav.) I had my bushings on the OEM sway replaced at the dealer and could have bought a whole new afternarket sway for the same money. And after 6 months, it squeaks again, allbeit not nearly like it did. Others suggest a replacement of the sways to a better aftermarket version (Hotchkis) with urethane bushings (in my personal plans to do so.) Either way, excluding something being broken (BJ/shock), I'd bet $10 right now that it's the front sway squealing.
