Betcha never seen this bolt before

I began hearing some very slight whining from my rear end (different from the normal grumbling my rear makes) :lol: so I decided to have a look and freshen up the gear oil. Well, I noticed a couple peculiar things.

The first was that the differential only had about 1/2 cup oil in it.

Now I’m certainly not a professional mechanic, but I’d say someone put a little too much Loctite on the bolts the last time they reassembled it. What does the peanut gallery have to say?
