hey, i know nothing about cars so im hoping someone can help. i have a 90 corolla (pos) and when i make turns my car makes a thump sound. It sounds like its coming from my tire area. Also when im stopped.. and start to go it makes that noise. the noise almost sounds like someone is banging on my car... it only does it once then stops. i dont know if thats enough description, but let me know if you have any clue as to what it might be! thanks!
