The 3.91 diff has a small leak, either the bottom drain plug or at the diff plate, can't tell which. Going to reseal with loctite 5970 and put some gasoila on the drain plug. I'm hoping I can do both of these without the need to put in new oil. The current oil only has seven or eight thousand miles on it.

Diff cover resealed and I put in a magnetic drain plug that has an o-ring this time. Coating of gaoila to go along with it.
