    That looks like a tooth from your pinion. Fix now. Or you diff will go clunk, clunk, chunk, bang, clunk, bang.

    I've been there. Could not move, even with inter axle locked.

    Yup, it’s only hours away from destruction.
    Always cheaper to do things now than later on the road with a hot load.

    Need to take a look for sure. Might get lucky and it was left in there from a previous failure.
