Diff leak

[72C3]

Guys and girls,
Got a new hoist the other day, love it.  Unfortunately you see a lot when you have a good look.  From my uneducated eyes, it appears I have a leak from the front diff seal area.  Given that my rear bearings are also a bit loose, what would be the best course of action.. Fixing it is obviously the correct answer here but do I need to do the complete diff removal.
Thanks in advance.

It's possible to change the seal with the diff in place .
But you need to know what your doing , to keep the preload as it was.
