Ok, here's what's happening on my 02 Santa Fe LX AWD with traction control
and ABS with 44780 miles.  When I am either maintaining or slowly
accelerating (10-15% throttle) from 35-45MPH I get a strange strong
vibration coming from the front end sometimes (About 20% of the time).  The
car does not pull to one side or another, and the vibration goes away if I
alter the throttle position (More or no throttle).  There is no noise except
for the vibration.  It also always shakes a little (Barley noticeable) from
35-45MPH.  Other than that it is smooth, no pulling, no warning lights ever.
I have rotated the tires and no difference was noticed.  And now a little
back ground info, about the same time the vibration started my car stopped
squealing.  The squealing happened after driving 5 miles or so and would
stop when breaks were depressed, or driven over 30 miles) otherwise it was
non-stop and loud, I checked the brakes and there was plenty of material,
and of course my dealer could never reproduce it and since I picked up after
hours, I was unable to show them.  After talking in the santafeforum.net
they told me it was a caliper problem and they just needed to be cleaned, so
I just dealt with it as I did not have much time or money to get it worked
on.  This went on for about 1000-2000 miles.  So my theory at this point is
maybe a wheel bearing went bad, and that was the squealing and now the
bearing is completely shot?  Is that covered by warranty?  If not on average
what is the cost?  Anyone have any other ideas?  Gas mileage on a 125mile
highway trip today was 22MPG done the scientific way (same pump, same gas
station, and filled until the gas was visible and did not go down anymore).
I have nothing to compare gas mileage to because it's my wife's car and I
never watched MPG, I just made sure it got regular maintenance, gas was
taken care of by the wife.  Thanks for any help in advance!
