Moaning Car?!

    I'm driving downtown to support my roommate at a
guitar competition 
(of
which he came in second) and I hear this odd
whining/moaning from the 
car.
I've definitely never heard this type of whine from a
car before.  It 
is
almost like a tuning fork is in the trunk of the car.

    I just recently discovered I have a bent stub axle
in the rear of 
the
car.  I had the wheel bearings replaced two months ago
in the rear, and
within a month and a half the right rear started
vibrating in turns 
above
75mph, which it still does now.  Though this noise has
only one 
component,
45mph, it doesn't matter if I turn right or left, the
car whines.  It
doesn't matter if I'm in gear or not, the car whines. 
I am totally 
baffled,
the car feels very smooth and sweet, no odd handling
behaviors, but it 
has
this horrid humming from the rear at 45mph, and if I
change speed by 
2mph up
or down the noise disappears.

    The only difference between yesterday and today is
a full trunk and 
a
Thule rack went up top.  I thought it was the rack,
but this the whole 
car
humming.  Then I thought it was the bad wheel
bearing/stub axle, but no
difference when I turn left or right.  No association
to RPM at all, 
just
45mph on the dot.  The trans shifts smoothly, so
hopefully not a 
whining
trans or diff, plus it runs Redline.  Everything runs
normally, but 
just the
whining in the rear, or so it seems to be from the
rear, very ambiguous
noise.  Anyone have a clue?>>

Take the tow hook out of the trunk.  I heard it weighs
allot so it may be making something rub :)
