I agree, have never drained a birf type diff that didn't have some moly in the fluid and if I did would look to see if the knuckles were empty. There should be some grease weeping past the knuckle, the balls should be oily and some build up on the wipers. IMHO as long as it's not birf soup, ie lots of gear oil mixed in the grease, it's good to go.

Grease is mainly oil suspended in a carrier, some greases give up their oil easier than others, so some oil is normal in that area.
The nuts holding the steering arm to the knuckle are known to come loose. When they do axle becomes misaligned to the seal, causing gear oil leak into the knuckle. If caught quickly, only slightly loose, they can be tightened and sometimes recover without seal damage. Most times they are run too long, sometimes studs back completely out, etc, then the seal is ruined and needs a full pack and seal job.
I'm not sold on the Marlin seals for the '80, have them, but haven't run them, so time will tell. My thoughts on them are in this post;
