Driveshaft Seal Replacement

[MattMostyn]

Apologies - expect this has been has been covered before, but can anyone send me the procedure for changing the above ?

De Dion with Sierra diff and I'm reasonably sure the RHS drive flange seal is leaking. A bit hard to tell as the oil has spread pretty much everywhere, including inside the rear wheel...

I did do a search, and remembered someone posting a link to a concise procedure, but cant find it on here or BC.

Any help appreciated as I'm going to have a go this weekend...Assume I can get to it with the diff in situ ??

Thanks
Matt
