Phil,
I had the same problem when I changed the hubs on my rear axle. The oil
seals, which are the ones that fit inside the akle tube behind the
bearings, used by Morgans are the old leather type. These are prone to
leaking and I've heard that old hands do not remove old seals but simply
put a new seal in on top of the old ones. I finally found a modern
equivalent neoprene seal used in a Jaguar (sorry I dont have the part
number). These worked a treat. The outer seal is really only a dust seal
and will not stop anything leaking out.
If you leave the situation as is you will find you end up will oil all over
your rear brake linings. Makes for interesting braking characteristics,
esp. on damp roads.
Cheers
Steve Moore
