so, any help at all would be appreciated
my 2 cents...
jack it up, spin the wheels one at a time- might find something stupid like a small rock in a brake, or if drum rears, maybe a something inside the drum, or even just rust in the water groove...if nothing else maybe if you get it up on stands and have someone spin the tires by hand you might be able to narrow it down a bit from underneath. if you cant hear it(with no weight on tires), maybe check out wheelbearings- my lincoln had a 'whirring' gearlike noise in the rearend, figured just from 140k miles of wear and tear on the gears, but checked bearings when redoing brakes and found bad one- changed them to the 'axle repair' types that moves bearing to unworn part of axle, alls quiet.
one other noise on the lincoln- the abs sensor star wheel rusted enough it was rubbing the sensor- it had a kinda high pitched scraping sound to it...
