Subaru Baja 2005 hearing noise (whine), at 40 mph and higher turning left only.  Mechanic rode with me for test drive to hear sound and put on rack.  Bearings all ok.  Mechanic suggested to get second opinion from Subaru dealer, consult with service department. 

Mechanic felt noise is in final drive and or transfer case.  

Other opinions out there, ideas as to what may be causing sound similar to bearing sound? 

Baja has 204k miles runs well, been a great vehicle.

Subaru wheel bearings can be very hard to diagnose - I might not rule that out just yet.

wheel bearing

 

Drivetrain noise would be constant in proportion to the speed, and not affected by turning.

 

only hearing it above 40, and when turning is most likely wheel bearing.

as a very unlikely possibility - brakes, backing plate/shield and maybe lugnuts should be checked. (though, prev. inspection by mechanic may have included all that...?)

Wheel bearing. Need to check them with a stethoscope while driving on a lift.

Wheel bearing. These hearings don't exhibit play until they're totally toast, so grabbing the wheel and rocking it around is not a valid test for wheel bearing noise.

Stethoscope on a lift is often the quickest way to check, but isn't always conslusive if there's no weight on the bearing.

Chassis Ear kit on the knuckle has always worked for me. Put one sensor on each wheel, drive it and see which on makes the most noise.

baja sean, did you get sorted-out?
