    Not sure it'll be the bearing as its a solid bearing and don't think you'll hear it if it could spin in the housing which is unlikely. It's more likely to be the turbine exhaust shield which had come loose if it is in fact the turbo. It's very difficult to give a full diagnosis on 2 simple paragraphs of txt, suggest you get it looked at .
