so whenever i drive and have the windows open i can tell something is rubbing against both my front wheels and there must be something in the wheel well. there's a big gap to look in, but i see no obstruction. it happens every revolution, it's like a combination of a chirp, hiss, click sound. hard to describe. something like a leaf or twig, but i see NOTHING. is there anything i can do to check? i just hope nothing is really wrong like my rotors or axles are messed up.
i think i can relate the sound to the rubbing you get when a leaf is stuck in your brakes on the bike, and every time the wheel hits it you hear the hiss, clip sound.
