possibly your tires or a wheel bearing, listen at lower speeds, if you rock the steering wheel back and forth and it comes and goes it's probably a wheel bearing
Remove the muffler
the wheel bearing on the vehicle will make a roaring noise when you accelerate the faster you go the louder it gets
sounds like a wheel bearing going out
it may be the drive shaft u-joints if its rear wheel drive
it does that because it has a generator which makes the engine makes these sounds
it means your brake pads are worn out and need to be replaced
It is probably a wheel bearing if it only does it while moving.
no--bearings and tires are the most likely cause of roaring--esp if it gets louder as you roll faster
Apparently it does. Try this at home: Light your torch and listen to the sound it makes while burning. Then blow it out with your breath, noise stops, why I don't know. I am still trying to figure out why it burns when I pee.
You probably have a "throwout bearing" going bad.
Most likely it is a belt on your car. Usually the squeeling is from a loose belt while idling and will also make noises while driving.
One or both of you're drive axle bearings is dry
