They usually whirr a bit more when there getting worn. Never heard one rattle before unless the wastegate is loose?, check the shaft for excessive movement.

it sounds like boost excaping out of a small tube loud wine not turbo wine but its from the turbo. its like a wheel bearing when ur on lite boost would the bearings be gone in my turbo.

Yes.

But when you have fitted it back together make sure it's on straight and the wheel doesn't catch on the housing.
