My jeep has been doing this since I've had it. Whenever i hit a small bump, turn hard, and sometimes when i just get in it i hear a quiet popping noise.
It sounds like its coming from the passenger side. I know its nothing like tire rubbing since i am still stock. It sounds more like some sheet metal rubbing against something as if a screw was lose or something.
Not super annoying, but wondering if my jeep is the only one that pops, or if anyone knows how to fix it.
