Ok so this whine from the rear of the car was thought to be gear whine. It has been getting progressivly worse and it louder/softer with speed like gear whine. But the car also gets a horrible vibration above 80 in the beginning but now happens around 60 under light acceleration. I got gears in the mail but I'm thinking I need to have a bearing or something replaced. I'll be able to rule out the gears in a week or so. I'm afraid to keep driving with this **** screaming at me. Any thoughts... Should I be less worried?

 

have you checked your u joints?
