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.

    I'm thinking it would either have to do with a wheel bearing or the drive shaft on the right side, but don't know for sure. Commented Feb 4, 2015 at 11:01
  • By "drive shaft", you mean "axle", right, @Paulster2? Not the driveshaft going to the rear diff.

  • @JoshCaswell ... Yes, axle shaft would be a better name, you are right. Commented Feb 4, 2015 at 22:50
  • Whatever it is, sounds serious. I've booked it in with my mechanic and will post an answer once it's fixed. Commented Feb 5, 2015 at 0:20

It could be the steering rack or bad wheel bearings.

It could be oddly worn tires or ..If the 'OutBack' means you go 4-wheeling in harsh terrain ,you may bend the frame of the vehicle even to the point of setting off the air-bags.

    By Outback, he's talking about a specific model of vehicle ... I'm pretty sure in this instance it has nothing to do with Australia. Commented Sep 5, 2015 at 16:07
