So Ive got a 2011 Manual Pro 4x and followed Rooks write up about replacing the output shaft seal upon finding mine was leaking and didn’t even have the dust boot over it. Ordered up a new seal and dust boot, and everything went smoothly. After the install and test drives I’ve noticed the leak seems to be continuing. Upon following other users suggestions I pulled everything back off but the seal, and used a mallet and pvc pipe again to make sure the seal was fully seated then wiped everything up. Took another test drive and found the same issue. I read from another forum that “the seal just needs to be broken in” so proceeded to drive it a few hundred miles, still the leak persists. What I’ve noticed is it’s not an actual leak, with drips and a puddle, it’s more like the yoke is slinging tranny fluid when I drive it around, because when it’s parked, there’s never any drips on the floor or under the car. Just all around the yoke and above it on the body of the truck. I’ve inspected the yoke fully, no burrs, nicks, or sharp edges. And the seal was brand new, no tears or visible issues. I’m at a loss for what to do, and worried that there could be a larger issue I’m unaware of so I haven’t been driving the truck. Even though the seal is cheap, I don’t want to buy it again and still not solve the problem. I’m not sure if the part numbers are different for my year, or if it being a manual makes any further difference. I appreciate and help or ideas

Old memory, did someone have problems with the shaft coming out of the transfer case running out and causing a leak?

Also, did you put the plastic piece in the upper right of this photo in with the new seal? (Not that I'd guess it would cause a leak if it was missing)

Yes I did, bought everything together and they looked just like that. Are they somehow different for 2011’s or manual transmission? Maybe the inner diameter of the seal or something is supposed to be larger? The packaging says: nissan group genuine part 33140-7s110 seal-oil rear

Mine is an '11 S with a 6MT, so I'd say it's the right part.

Seems like it would be then. Only thing I can think of is throwing another new seal at it. How far out is your yoke sitting? I only ask because the only thing I’ve noticed is there’s a small beveled edge on the yoke closer to where it connects with the driveshaft, I’m thinking maybe the yoke needs to be seated in the transmission more so the beveled edge can sit against the seal

I'm nowhere near my X to look, but doesn't the position of the yoke slip on the output shaft as the suspension/axle moves up and down?

Yeah it does, that’s why originally I didn’t think it mattered what length was exposed, but then it shouldn’t be leaking at all. Just trying to get a general idea of other X’s and what they look like, maybe the beveled edge I mentioned actually does something with matching up with the seal
