Hey guys got a question a little bit off topic. I have an 04 1500 ram with only 33,000 miles and im noticing a noise coming from the engine. Its like a low humming noise that only seems to occur when i come to a stop. It sounds like power stering but im not turing the wheel. Could it have something to do with the brakes? Is there any known problem with the 04's that i should be made aware of?
