i have a 98 honda accord and just recently, i noticed a humming noise coming from the rear of my car when i am driving. when i am stopped at a light, it goes away, but when i start driving again, it comes back. what do u think the problem is??

 

There isn't a lot back there to hum when you are moving. I would think it would be either your brakes or a bearing. First thing I would do is check the brakes.
