Drive shaft bearing noise?
If so what were the symptoms that you had with the car?

)If the flex discs have cracks in them they need to be replaced, jack your car up or put it on a lift and use a flash light to inspect them.

I suspect it might NOT be the bearing since I still get the vibration even if I slow down in neutral (which should unload the driveshaft) which would eliminate the vibration. Nothing I try impacts the vibration. It's always there as I pass 15 MPH.

Here are some pictures of the bearing that failed.
yesterday I took it to your neighbors ( he is a mechanic but young about 19 years old )i am not sure he is a specialist i this kind of cars but he check it and told me that the drive shaft has a problem in the middle (like a space) he moves it and hear a knocking in the middle like a space in
he told me that it is the problem but I was worried if he isn't right because the sound and the vibration is very hard and I think it is from the gear itself or a clutch in the gear and when he check and move the drive shaft with his hand up and down the gear was in neutral
IS HE RIGHT A SPACE IN CENTER OF THE DRIVE SHAFT MAKE THIS NOISE???AND WHY IT IS JUST IN THE FIRST GEAR NOT IN ALL
