Over the past few days i've noticed a noise coming from the front
end.  Sounds like a wheel spinning.  There is no grinding or much
vibration.  Gets louder at higher speeds.  147K on it.  New pads on it
about a month ago.  Although it is 4x4, we removed the front axles a
couple of years ago due to damage (wasn't worth repairing).  Trans
fluid is clean.  Friend mentioned harmonic balancer.  That sounds like
I should have a lot of vibration.  I don't really have any.  Car is
acting like it always has - no shifting problems, starts fine,
nothing.  I did put the car in Neutral at 60 and noise did not go
away.  Trying to avoid hefty bill for paid off car.  Any mechanics
have an idea.
