Believe it or not I am still having this issue, I haven't been able to figure it out 4 years later. But tonight I went under the car again and took a look at the driveshaft and next to the center bearing was what looked like old old grease. Then another u-joint had mine spots of old old grease and considering that these are supposed to be sealed I would say that they have gone bad. Any thoughts?

Thanks for all the tips! I decided to rotate the tires and yet it was still a vibration in the rear. I believe that it may be the drive shaft because I did do the clutch myself a year ago and had to remove it. I may have knocked off a weight or misaligned it, although i made sure i replaced it in the same way it was taken out. I am thinking it will have to go to a mechanic for a sure test because of what I am limited to being able to do. Thanks again for the tips, at least now I have some ideas to base my problem off of.

Hi, I have a 1998 subaru outback legacy Standard transmission with 138K miles, that I am experiencing vibration problems with. It occurs at 40-50mph and is a loud low noise, like the opening a window at highway speeds. It is most felt in the seat of the car which makes me believe it has to be from the back as the steering wheel does not vibrate. I don't believe it is the tranny because i can't feel the gear shift vibrate. It does not vibrate until that certain speed. It seems to go away with speeds past 55mph. It is not the tires as I have had them done, along with a wheel alignment. During the summer I can barely notice this vibration, although it is still there. It is the worst in -4 degree whether and as the car warms up it seems to not vibrate as much. I hope you can give me some advice, I have already read about wheel bearings, drive shaft issues, tranny issues, but i can't quite pin point it. Thanks very much!
