Actually it does it anywhere but it is louder on the freeway comes out of the rear wheels, it sounds like the left wheel.
It started out of the blue, loud humm, if I am on the road on a slight left turn the sound goes away, when I agoing straight it comes back.

I got new tires balanced and an alignment everything checks out, I don't know what it is, the sound is till there.

Any help is appreciated, I have been annoyed for about 2 months now.

Thanks

 

It could be your wheel bearings.

Cheers,
Sean

 

I agree, wheel bearing.

 

How difficult is ti to replace and how much does one cost too?

It seems simple in the manual, minus the hassle of rear disc.
