My 2008 Subaru Outback has a gentle vibration I can feel in the steering and accelerator pedal and also a bit of noise associated with it.
At first I thought it was just the road but I noticed it gets slightly worse when I turn left and goes away completely when I turn right.
It feels/sounds like driving on rough asphalt.
Any ideas? I checked there's nothing rubbing on the wheels and power steering fluid is just bellow the "Max" marker.
I also tried putting gearbox in neutral and rolling through some fairly sharp corners at about 60kmh, it vibrates exactly the same as while driving normally - so probably not related to the engine or transmission.
