2011 Jeep Compass weird noise @ 20 mph

Hello. My 2011 jeep compass has been taken to the dealer for a whoomping noise coming from the r/f tire area. Every time I drive around 20 miles an hour it sounds like something is stuck in the tire. As I drive faster the noise gets faster then eventually stops around 45 50 MPH. Dealer checked and balanced all tires as well as changed both front hub assemblies. Noise is still there. Dealer says there’s nothing else that can be done. Is there anything I can check that they might have over looked. I’m a big fan of the show. I work at Mack trucks in eastern pa as a repair technician. Working on a6 electrical cert. Any suggestions on my weird noise coming from r/f wheel well.
