Once I drive for 50 miles or more, I begin to hear a loud whining sound. I took it to the shop, they said my wheel bearings were worn out. They replaced the bearings on the wheel. I got my car, took another trip, still heard the loud whine after ~50 miles of driving. I took my car back to the shop, they replaced the set of wheel bearings on the other wheel. Now I've been driving 50 miles, and I hear this sound again.
If you've ever wound a hand-crank charged flashlight, its exactly like that sound. Identical. The faster you wind, the louder the whine sound gets. And then it continues for a moment because the spinning part inside is spinning for a second or two after you stop cranking it.
Well that's exactly what happens when I push the gas pedal on my car, but only after driving a long distance.
Are these details enough for someone to know what component of my car is having a problem?
