Need some help guys, FQ300 Manual 2008 driving 50 MPH and upwards any gear i can hear like a whining/humming noise coming from the rear of the car, but from 0-50MPH no noise. What can it be? Or is that normal on the Evo X?

 

How many miles on the car!? maybe tires going bad!?

 

8700 miles Got new tyres on.

 

Sounds like rear diff or maybe a wheel bearing, but more diff. Does it change how it sounds when you accelerate/cruise/decelerate?

 

No sound does not change but the sound is only there anything 50 MPH and stays at the same level of sound.

 

As racingguy13 said, does sound similar to rear diff or wheel bearing. I have experienced a wheel bearing go out and it sounds somewhat similar except the whine would get worse with acceleration, not with speed being traveled.
