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.

thanks guys,

It's either your diff or your fuel pump if the noise is comming from the back of the car.

have you replaced the diff oil (make sure it's LSD stuff) and added some lubrizol??? Might be a starting point if the diff is from the wreckers.

Sounds to me like your diff gears may not be real healthy, possibly bearings as well.

yeah I cleaned the diff out and replaced with good quality oil. It was fine when i got it, but just started getting louder and louder on a trip from Adelaide to Syd. Its been the same ever since (6 months or so).

I've been meaning to change it out but I'll try something else if it's easier! :)
