Check sway bar. On some models as suspension sags, sway bar outer ends will contact the body, leaving a mark or dent just above the end, causing a bang over bumps. Only way to correct this is to change springs or add a spring lift.

I think there is a TSB on that problem. If the wind is coming from the passanger side then roll the window all the way down. Put a 2X4 in the door jam. So the 2X4 will be inbetween the the door and the jeep. Push on the top of the door like you are trying to close the door. What you are trying to do and slightly bend the top of the door toward the jeep. But just do it a little at a time.

If it is new take it back to the dealler for warranty repair. No new vehicle should have any noises . seriously, take it back for repair.
