From what you write, seems like either a half shaft, or a drive shaft...

If it were a wheel bearing that was nuked, you would feel it in the steering wheel, and when you had it apart, you would be able to see it.


Halfshafts don't usually whir so much as graunch (lower frequency). If it is a whir then it could be the support bearings in the diff, or if the noise is in the LHS the bearing in the end of the diff case near the LHS halfshaft. Driveshaft would not be an issue if the vehicle is not in 4WD - if the noise is present in 2WD then it is not the driveshaft (tcase to diff).

As a guide, bearing noise will usually present as a modulating volume whir as the bad balls roll past the bad area of the inner bearing surface generally at a ratio of about once every 3-4 revolutions of the inner surface. DOJ/CV noise will be apparent as a 1:1 ratio low rumble with knocking on corners (a characteristic "knockle" sound), generally the direction you turn with the loudest noise will be the side with the bad joint. A cyclical 1:1 ratio sound is usually tires, or warped disk/loose wheelbearing combination levering the bearing a bit per rev.

Before going any further though, HAVE YOU SWAPPED THE TIRES AROUND IN CASE IT IS SIMPLY ABNORMAL WEAR ON THE TIRES (feathering)?
