Roads that are patched up will cause a thumping noise especially if you have too much air on the tires. That is if the noise is coming from the lower part. It also could be that a rubber grommet has fallen out off the sway bar and is hitting medal on medal. If the noise is coming from the roof, it could be your bat wing antenna moving up and down, striking the roof.
BUT? Ray he said only when Windy and too much air has nothing to do with wind conditions Now the batwing antenna on mine was banging when windy
