I've done some more research...talked to other owners, talked to the dealers, etc. I think it is generally a characteristic of the vehicle. It only seems to happen at certain speeds and RPMs. I can actually control it if I'm careful. Hopefully it's not a problem. I've got an extended warranty if it becomes a problem in the future.
Good luck with your '04. Let me know if you find anything out.
