A friend of mine has a NBS 07 LMM and he's been having all kinds of trouble with the output seal on the transfer case. I believe he said he's replaced it over six times and it keeps blowing out very quickly. The underside of the truck is an absolute mess. It's been slinging fluid all over the place. My thought was something on the yolk was tearing it up, but while I haven't seen it myself, I'm told there's nothing wrong with it that would be shredding it. Has anyone else seen troubles with the seal on the NBS trucks? It's a CCSB with a single piece DS.
