Disco 1 Tdi 200 1993 the boy found that the front output flange seal protector disc had come loose and was rattling around the flange. From inside the vehicle it sounded expensive. I ordered a new seal and Speedi Sleeve to repair the flange. The boy came back with a new flange assembly including seal/flange/disc/felt washer/steel washer and Nyloc nut with a price that was less than the seal and Speedi sleeve, good result good lesson. Thanks MR Auto
