R1100S drive shaft leak

My little S sprung a leak yesterday at the rubber bellows that cover the uni joint at the FD.
I figure it could have come from the rear gearbox seal however the bellows at the gearbox are dry with no sign of oil.
Im assuming that there is also a seal at the shaft input at the FD which may have failed? Pinion seal?
I recently changed the FD and Gearbox oil over to synthetic which is much less viscous than the regular stuff and this may have expedited the leak.
Any advise, stories, pictures etc will be most welcome.
How bad is this bad news?
