Default Help find source whining noise?

Went to the track and now it is making a whining noise. I believe it is coming from the rear end. Doesn't make the noise when swerving side to side or making sharp turns. Changed the rear fluid and it is still there. Volume increases with speed. Comes on only on load and completely goes away after I let off the accelerator.

Try it with out the wife in the car.







Sounds like you may have lost a pinion bearing, get it fixed fast or you'll lose the gears too.

Check your rear Axle Bearings & Wheel Bearings moving the car from side to side transfers weight and can be a bad bearing changing tune by the amount of weight your putting on it

Did the whine start before or after the fluid change?
Did you remember the limited slip additive?

Tried side to side movement but no change in tone. Noise is only there under load.

sounds like the pinion bearing in the diff. Possibly even a crack in the pinion bearing housing. But thats just a guess without opening up the rear.
