when i changed my front diff fluid, with had never been changed, i notice that in a couple places where the two haves met, it looked a little "wet" like some sepage, not much but a little, is this anything to be concerned over?

 

Mine has had that since day 1. 150K now and no issues. I just change it every 30K or so.

 

If its not dripping bad I wouldnt worry about it mine looks wet around the joint to but it has plenty of fluid in it.

 

that is what i thought but i wanted to make sure
