So it sounds like a little of both from underneath the front of the car; like when some cars go in reverse to give somewhat of a reference.
Neither braking or disengaging to clutch stops it or makes it any less quiet. The only thing it really correlates to is how fast the wheels are turning.
I've changed the tranny fluid and the rear differential just to be on the safe side but it has made no positive difference; in fact the problem seems to be getting louder and more stressful.
Whatever the problem may be, I'm thinking it's beyond my realm of experience, so any information that I can make some sort of diagnosis to either fix myself or take with me to the mechanic so I'm less likely to get raped would be very much appreciated.
God help me if it's the tranny!
