2016 AWD Rogue SV Transfer Case O-Ring seal leak?

[darrylwmiller]

So I had numerous issues with an independent tech who installed an after market CV axle which then lead to a leaking Output shaft oil seal leak. Tech replaced with new OEM CV axle and replaced oil seal and dust seal. The leak stopped but now I am noticing a very slow and small leak at the bottom of the transfer case where the cover meets the transfer case body.

I looked up an exploded view of the parts but I don't see any talks of this on google. I am assuming this is uncommon and just wanted to know if anyone else has had this problem and if replacing the O Ring between the transfer cover and the transfer case likely stop the leak.

unclear to me - you are talking about seal leak on shaft, but you post pictures of drain plug...

Those o-rings practically never leak, you're right that it would be very uncommon. The first thing I'd do is clean up the area and add some UV dye to the transfer case, to verify where the leak is coming from. If the guys who did your axle cracked the case or something, you need to know about it before you tear it down replacing a gasket.

Seal leak was fixed with new oem axle and new oil seal. The leak I am talking about is the verry bottom of the transfer case where the cover meets the transfer case itself.

I cleaned it previously really good and even broke out a small tooth brush to get all the spots in that area. After driving 200km I can see a small build up in that exact spot that I circled. Very minor amount. I do not see it coming from anywhere else.

it looks like "top" part of casing has U-shaped cutout... either disassemble and put some sealant there or clean it and put some sealant from outside...

Thank you, will give that a shot. Any particular kind of sealant you think would work best?

doesn't matter. just properly clean it and don't use " one laying around since beginning of the world".
