Revised seal, different diff. Well throw that out the window 2013 journey now 6,000mi has leaking diff guess the updates didn't help. And I know all about no one makes a perfect car as I am an ase master tech myself and this is ridiculous they have been out since 09 bugs should be worked out by now. Wish I would've did some research before I spent 30,000 on a car with these problems.
