While driving normal roads I turned off my music and noticed a roaring sound louder than normal, it continued at all speeds, it continued when I put the vechicle into neutral so I assumed that it was not the motor or the transmission. Right or wrong assumption?? How about tries, alignment etc, or something else /  any ideas .  Thanks

There is no change in the sound when braking, in reading some of the other posts it could have been related to the cold transmission fluid as it was in the teens when I noticed the sound... I check during warmer weather. Thanks for your input...g

Or worn tires
