The Nissan Path

So I am leaking at the seal behind the front propeller shaft coming out of the transfer case. Anyone else had this problem? Does not look to hard to do but am looking for some heads up on what to watch out for.

Any help is appreciated.

I've had that seal and a pinion seal replaced a couple of times at the dealership. It's cheap and it doesn't take them long, so it can't be hard.

Those seals and the serpentine belt/tensioner are things that go bad about every two years for some reason on my truck.

Remove the front propeller shaft, remove the nut, use a puller to pull off the yoke, use a seal puller to remove the old seal, reverse to install. Top of fluid as necessary.

Thanks, ended up taking about 5 hours with a trip to the local auto store. Did not have the 30 mm socket to remove the nut holding the flange. Now time to do the timing chain tensioner.

Both my front and rear outputs are leaking on my T-Case. The rear appears to have an outer dust cover or boot? Is that separate from the seal? And should the nut be replaced or will it hold its torque? I know on some other vehicles yoke nuts are supposed to be placed after removal.

Check your breather tube, I'd bet real money its plugged.

That's especially true for rear diff. As breather tube is clogged and you dive with hot diffs into cold water, diff will not be able to take a breathe through breather tube, so it will instead pull WATER through all possible diff seals into the housing.
So you could have some diarrhea-like fluid in your diff instead of clean oil
