NSG370 M/Trans rear output seal...

UPDATE - Aaaarg. So get this,... replaced my transfer case input seal, which seemed to be the cause for the slight leak, and... it's still leaking! Any ideas, anyone? Wasn't any play in the input shaft from what could be seen or felt... But obviously something isn't right? Anyone have any suggestions or ideas here? Should I just find a new transfer case or get this one rebuilt? Or...? Suggestions please. :I

---------------------------------------------------------------------------

Yeah, I know it's probably wrong, but I'm double posting this....

Anyone know the part number for a replacement? Be it a MOPAR, TIMKEN, or other?! Went to two dealerships and they couldn't find the correct seal.. Really in need of one since mine's leakin'. Oddly enough, this has been the hardest part to track down that I've ever come across.

Do you have mild seepage around your bellhousing, is that why you are looking to replace?

I have had that since I got my JK at 21K. I am now at almost 40 now. I understand it is pretty common

I have... mild sweating/leakage coming out the weep hole between the transfer case and transmission. It's pretty mild though... Maybe a few drops every couple days so far.

Oddly, I think Chrysler put ATF in my transmission last time they did the 1st gear syncro TBS... and then a week ago I drained the red fluid and put in the proper clear NSG370 fluid and shortly after... leakage!

Anyways, yes.. slight leak. Doubt more than a drop or two has actually hit the ground yet.

As stated, I think seepage at the bottom of the transmission (bell housing) is considered "normal". IDK I may be wrong, but I think that most 6 speed owners here would state they have some seepage as well.

As far as I knew transfer case and tranny run atf+4 is there a big difference on fluids I'm in a 08 2 Dr auto I have the same small amount of trans fluid dripping

Bead of silicon on the seal? As in the middle of the seal where the input shaft would spin in it? Suppose that might help slow the leak... Really just want remedy the problem, not just Band-Aid it. Might start looking for a rebuilt/used/new transfer case. Shame the NV241OR is so pricey to replace.

As for you akjk, seeing as you run an AUTO it probably IS ATF+4 in the tcase and tranny. Seeing as I run a 6 speed, it's ATF+4 in the tcase, and Chryslers special blend for the standard trans.

Forget about it and move on. You are going to drive yourself nuts trying to eliminate a leak that will most likely never be eliminated. Keep an eye on the fluid level
