    Follow the chain

    Did an SYE (Rugged Ridge) last year same time roughly. Never noticed the main shaft sitting low before. Only when turning the shaft as its sits now did i see it binding a little. This leads to a mechanical sound coming from within. I split it and this is what i have. Ive taken parts from another NP231 to bring mine back up to snuff until i saw the chain.
    So.....any harm in shimming the main shaft up to the same as the front output shaft?

    did all the shims go in the right way on reassembly?

    ....been a while since I've been into a tcase so cant remember off the top of my head

    on edit: don't forget too that without the end case on, those shafts are not parallel and will give you some of that sag seen in the chain....but may not explain what may look like different heights.

    When i did the SYE last yeah there were no shims to put back in. Kinda gets me thinking maybe there should have been and someone had been in there before me.

    Only thing i can come up with so far is the main shaft pilot bearing is wrong. May have needed the capped bearing instead of an open style?????

    Have you tried putting the front output yoke back on and torquing it down?It might not be pulled all the way in

    Yeah ill give that a shot tonight. It looks and feels flush when seated in the front output bearing but anything is worth a shot.

    Also the chain has slack in it. Look slike it's just sagging in the middle from here.
    But our trip was different. It was to be a classic affirmation of everything right and true in the national character. A gross physical salute to the fantastic possibilities of life in this country. But only for those with true grit.

    And we are chock full of that, man!

    Swapped the chain and the gears and shimmed the shafts so they align. Checked all shift positions and she works slick.
    On a second note, i still have the same noise i went in with. Ah, the life of a Jeep owner LOL
