Hi guys,

Dont know if anyone can give me any advice. Recently I put my car into Audi for a diagnostic on a noise I had for a while but couldnt pinpoint what it was. I thought it was a wheel bearing but Audi have said that its a noisy rear Diff.
They want 3,500 for a replacement but Im trying to find out if they can be repaired or refurbished and what sort of place would do it, have any of you had any experience with anything like that?

I live in Norwich in Norfolk but am willing to travel if theres any places anyone can recommend.

Thanks
