Default Help T56 noise! Working Video

Please help me diagnose this noise. When clutch is pressed in it doesn't make the sound, when I rev it in neutral it doesn't make the sound. It's only when I'm gliding/lightly accelerating. Trans probably only has 10,000km.

Sounds like rear end whine, not transmission related.

I pulled apart the rear end all is fine. It's back together now. Changed Trans fluid and it made no difference.

The noise only happens on acceleration.

Ring and pinion gears can exhibit good contact patterns and the bearing could be fine, and you can still have noise.

Does the rear use OEM gears or aftermarket? Certain gear ratios tend to make more noise too. What's your ratio?

Update: Put it all back together, took it to a guy who is more of an expert then I am. And he was 100% sure it was the diff, hold your head out the window and you'll hear it from the diff. Needless to say I put in a summit order today for some 3.73's and a trutrac.

All the bearings were in good shape?
