PS wheel bearing

[Ed Kellock]

I would suggest that your difference in bearing noise is a function of
the size of the wheel primarily and possibly somewhat of the tire.
Geometrically, with a 8.5-inch wide et30 wheel, you're putting more
leverage on that bearing since more of the wheel/tire is further out
away from the center line of the car.  Basically you're leaning no the
bearing harder and more unevenly.
