Help pinpointing suspension noise and abnormal tire wear?
 

Just bought a low mileage mx3

Symptoms:

It sounds like it is possibly coming from the front end?
-Weird humming/growling when driving that is generally relative to speed, I don't feel it in the steering wheel, car holds straight lines solidly, turning left the sound tends to lessen or become completely quiet and turning right doesn't really affect the sound.
I also have fast tire wear only on the back right tire.
Also the steering feels a bit on the heavy side but it might just be normal and just not what i'm used to.

I initially thought it was a wheel bearing and I lifted the car up and did the basic wheel movement test and really didn't notice any excessive movement or hear any noises.

Are you sure it is not the tires? Rotate them and see if it makes a difference.

Maybe the brakes are dragging?
