Try this:

Under the car, on the steering column right before the steering box, there's a fitting with a pinch bolt on it.

That bolt (#9 on diagram below) needs to be tightened to 22ft-lb.

It's on page 2352 of 2004_Crossfire_Service_Manual.pdf , which you should get if you don't have it already.

Now would be a good time to replace your steering stabilizer if you haven't. They're very cheap (<$50) and tend to go bad.
