Unhappy Differential Fluid Leak?

So finally starting to look into fixing the fuel gauge issue has me discovering something else...

Looks like it's coming from here...

So I use my amazing mechanic skills and wipe it off with a rag.

Replace the gasket or diff. Lol its going to be quite some work. When I replaced my diff I had to take my whole exhaust system off and so on.

You know what. Actually the best way is to just remove the cover and reseal it. Check for uneven wear and metal shavings. That way you won't have to take the exhaust off. My bad about the first post. I replced my diff because it was bad. Yours look repairable so taking off the exhaust is unnecessary

Still don't know what Car you are working on KNIQ..is that an FB?.(remember state your car for quick answers).
anyhow,I fill until the diff fluid starts to run out the Fill hole,than Replace the fill plug.
My FC was a quart and a half or so.

Fluid capacity should be in the FSM

Just to get the guys to remember it,In This Section,it is advised to state it in the thread.That way the Reader sees it while glancing at the thread.
But hey SIG's work too,if they get looked at! Good to have once you get out in the Open Forum.

BTW:Love the glasses KNIQ..lol!

I'm having trouble finding replacement gaskets online and one of the youtube videos I watched featured the use of a tube of silicone gasket maker (I think). Is that what you all would use or am I just not looking in the right place for a conventional gasket?

I use "the Right Stuff" by Permatex for alot of my gaskets.
You can always make a gasket KNIQ and then skim the part and gasket with Right Stuff and then put it together.

Well that stuff has some pretty solid reviews, so I've ordered some. In anticipation of getting this thing done, I tried opening the drain plug with a socket wrench to no avail. Makes me wonder if I'm doing it right or I need to bring out a cheater bar...

Also, how do you get the cover off this thing? I think all of the pictures I've seen of diffs had the bolts on the rear side. I can feel some on the forward-facing side of the housing... but I'll have to redo my lift situation to be able to see them.

Hmmm.
That is an FB rear..Not familiar with it..but that looks solid where the "leaking" was wiped off...lol..with your madd Mechanical skills!
I'd investigate further Kniq and see exactly where it is pee'ing out.
Diabolical1 may be able to jump in on this.
