I have a "whirring" noise coming from the rear on accleration and deccleration. It does not occur if the clutch is disengaged or if i match the engine speed exactly to the road speed (i.e. no real load on the drivetrain). It has been doing this for quite a while now with no other noticable side effects. No clunks or different sounds when turning etc.
What does this sound like, diff bearings or maybe the driveshaft joint??
car is a 5 speed EA with an LSD I found at the wreckers.
