When I get to about 25 mph, there is a roaring sound. My car sounds like a jet engine to me.

Does this sound like it is coming from a tire area or the engine area? This is most likely a wheel bearing but it could be the engine fan so we need to try to limit down where it is coming from. Also, once you start to hear the noise does it get better then worse when you swerve from side to side like you are trying to avoid a pot hole?

Here is a guide that will help with the understanding what could be happening:

Let me know if you can get a recording of it and that should help as well. Thanks
