Transit connect problem (help please)

[Nedges]

Hi I have a 1.8 tdci torneo connect,its been an ongoing saga with funny noises coming from lots of different places,all because of a exaust gas rec valve that has leaked down onto the drive shaft over a period of time.changed both wheel bearings no problem,but there is a bearing with a shell over it on the drive shaft,ford dont supply the part you have to buy drive shaft,er dont think so the job looks easy enough so any help would be great if someone out there knows where I can purchase one. Thanks John.
