Thanks for the pointer. Unfortunately my account on there has still not been activated (27th May) so I'm unable to contact him at this point. I've emailed the websites contact email in hope that they will activate my account shortly.

 

I've managed to locate a used transfer case locally. Mine is now removed.

Just a quick question - is it usual for the Transmission to leak its fluid from the output shaft once the transfer case is removed or does that indicate a bad seal? Visually it looks fine.
