Hello Tech needed...

Since collection my car from the body shop (after the respray), I have noise/vibration developing from the diff area...

The diff has been making a noise like its on the way out for some time now (the usual wine), but this very different.. coming from the rear middle of the car... a sort of slipping/thudding noise with a sort of thudding vibration...
This "thing" only seems to be happen when pulling off from being stationary. and doesnt last very long, if I reduce the acceleration the noise and vibration goes. I have only been driving around london since I got it back, so havent fully test it yet. but

Does any of this sound familiar?

Does anyone know what happens when the LSD fails in the diff?
To be honest I don't know much about diff's/LSD diff's. Is there a sort of clutch that is failing inside?

Any ideas?

Many thanks

Gareth
