Question about 2004 Chrysler Pacifica
I find the analysis that a rusty engine cradle would cause this problem.
My wife's 2004 Pacifica had a similar problem. When driving in roads with expansion strips, every strip caused a sound like something hitting the bottom of the floor. After going to the second dealership (the first one said they couldn't replicate the problem), they replaced all the front suspension bushings (under warranty with 69,100 miles on the car).
The car is now at peace and has remained so up to its currently 88,000 miles.
The other thing I recommend is to get rid of those junk Michelin tires. We replaced ours with high end Goodyears and the improvement in performance, mileage, and handling has been incredible. Traction in wet and winter weather was also outstanding.
We love it and are looking at getting another one.
Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

If it sounds more like it's coming from rear of engine, that could be a possibility, and should be followed up,but if it's coming from front of vehicle area, I'd concentrate on your accessory drive belt . If it hasn't been changed in quite a while especially. That belt is routed around about 8 different pulleys,in,out,over,under, and it would lead me to believe it would be a good candidate for wear & noise that would increase as it wears more. I wouldn't try belt dressing as I'm not a lover of that stuff, only for emergencies. It may be as simple as spraying water on it to see if the noise changes or disappears, just keep your eyes back if engines running. They make what they call an audioscope, basically a set of headphones wired to an amplified probe, so it's easier to isolate the noise, perhaps a local garage has one, and can pinpoint it for you. Years back mechanics would use a long screwdriver or pipe up to their ear and poke around, but that's very dangerous, so I wouldn't recommend that. Your engine does have a timing belt too, and engines in the past have been known to produce that sound you describe from wear on it too. I'd go after that one as a last resort unless manual recommends it at certain interval.

It sounds like pads against the rotors. Does it get louder or stop when applying the brakes?May be a stone or maybe just rust or maybe you need brakes looked at.

I have Chrysler's 8year 80000 mile max care warranty and Chrysler just spent about 4,000 dollars replacing my engine cradle. HAVE ALL PACIFICA'S CHECKED FOR RUST ON ENGINE CRADLE IF IT IS RUSTING CALL NHTSA THEY WILL TAKE A COMPLAINT OVER THE PHONE. YOU NEED A RECALL ON THIS ALSO CALL THE BETTER BUSINESS BUREAU
