Hi Guys,could use some help with this one....About a month ago I started getting a roaring/vibration sound coming from the back of the car,took it to a repair shop I use and they said it was a bearing,changed the left rear bearing and the noise went away for about (3)day then it was back...even louder than ever! Had the other (3) bearings changed and i still have the noise. not as load as before but still load.
when Im on the hwy I can hear it,if there's a curve going left the
the noise damm near go's away! When I go around a curve going right the noise is at its loudest. The noise sounds like its coming from the back then again im hearing that Sh*t in my sleep now!
now the repair shop says they "Think" its the rear diff bearings/
The car has 130,000mi on it.
Has anyone gone through this??? Or can shed some light on it.

i have you checked your rear differential fluid, you could be low - and in a turn it is even lower in spots.
