[GeoHacker]

yah , id drill a 1/4" hole there... tell tail.....

cheers

Mine says M21 in big letters (same M21 is also on Transfer?) Code in the first sticker has an N in it, which would make sense, since mine is 1992.

I think I will drill a weep hole.

Inside the spacer case, opposite the transfer input socket, there's a red grime in there, like clay paint, red mud color, hard to get off the hands. The socket for the input shaft is all red inside, and the red rusty crud was also dry-caked on the splines when I removed it…

Old GL-4? Or perhaps assembly grease? Slung about and evaporated? If not grease, I think that might explain my low trans oil level…leaking seal there at output shaft…mystery solved. Surely not red loctite?

Transfer case seal has no leakage indications. Could swap it out since I'm there.

Should I grease the output shaft splines before inserting into Transfer case? (lightly?)
