    Happens occasionally, some talk of it on the off road forums. Some have replaced the snap ring with "Gilly's T-case saver", do a google search...

    It's a two piece collar that you cinch on the shaft with allen screws and replaces or eliminates the snap ring, supposed to be a better fix.

    I put in a TC saver the last time I rebuilt it. The snap ring was interior of that, on the other side of of the output bearing.

    So is it that the T-case saver acts as sort of a back up, in the event the snap ring was to fail?

    No the TC saver replaced the rear snap ring. My problem was a snap ring inside the case. I think it was inside the rear housing on the inner side of the output bearing??? At any rate, it allowed the shaft(s) to move and destroyed the range fork and then the synchro springs.

    If it weren't for bad luck, I would have no luck at all....

    Got it all back together and drove it around town. Pulled the truck back into the shop to fix a loose exhaust and saw the TC leaking along the midline (must have had a space in the gasket material??).

    I pulled the TC out again and when I pulled it apart, there were needle bearings floating around?????after only 4 mi!!!!!!!!!!!!

    One of the needles got into the oil pump and ruined it but that was it. Turns out the pilot bearing for the mainshaft was either defective and/or I messed it up? Got it all back together tonight with a new pilot and oil pump. Wish me luck everyone, I need it.
