Despite the fact that everyone here is mentioning U-joints, I suspect
that you are experiencing some play in the rear-end. Chrysler products
are notorious for this as well as other read-end noise as they get older. 

If you can reduce you idle some it will help. If you want to spend the
bucks you could have the rear-end rebuilt but this is typically
expensive. My best suggestion is that you just live with it. As noisy as
I have ever heard any chrysler rear-end I have have never seen one fail.

I had a 1974 Dodge Monaco with the posi rear-end (this was the first
year they went from the plates to cones in the posi rear-ends) that
would vibrate the hell out of the car under 15 mph. However, the car
still went for over 100,000 miles and died for lots of other reasons
NOT including the rear-end.
