I have a 96 integra se and have a weird noise coming from the pass side rear tire. Everytime the tire goes around there is a pinging noise coming from the tire. I pulled the tire to see if there was anything caught in the rotor. Last time this happened there was a rock that was caught causing the noise. Nothing at all was caught and I can't see anything. I spun the tire on the driver side rear and it felt free compared to the pass side almost as if something is grabbing the tire. help

 

Could be bearings maybe?
