I can get pictures of where the leak is dripping from, sure.
I'll edit them into this post when I get them.

Edit: Put pictures in.

In the first and second picture you can clearly see a drop starting to form on the knuckle.

Sorry for the pictures being huge, don't know how to resize them to fit the window..

Yeah it could be leaking as you can see on your exhaust that burnt black section. This could also be the transfer case leak as well. But normally ujoint grease isnt pink. So depending on the color of the fluid on the yoke i am going to say that your shaft is scored and is causing your leak.

The liquid on the yoke is red transmission fluid which is why I originally thought it was the seal, but after changing it I see the leak is in the exact same spot.

What do you mean by a scored shaft?

Thanks Boss

If its red its from the transfer case not ujoint. When I said scored I mean the shaft might and most likely has small microscopic scratches on it. These scratches will allow oil to seep through them as passageways. You can replace the seal, but its rubber will not be able to close these passageways if you will. The shaft may need to be replaced. Fill the transfercase and let it be for a week. Then check the fluid level. If it is still pretty much full. Then I would leave it alone and fill it every couple of months. Or replace the shaft and yoke.

So since the liquid is red then it's probably a scored yoke/shaft and not the u-joint? Is that right?

Also use very fine sandpaper on it and grease the seal. Even if it is slightly scratched that will stop it from leaking with a decent seal. It needs to be pretty bad to be unrepairable.

Sorry for not understanding but you're saying I should use fine sandpaper on the shaft and yoke? Also what seal am I greasing here?

You can sand the shaft slightly, but if they are deep then sanding it wont help, but worth a try. And I am not even sure on the greasing part. I mean you would normally put some ATF on the seal where it contacts the shaft so it goes on with out rolling, but I haven't heard of putting grease anywhere on it. Overkill should explain more I suppose.

If it is so bad that you sand it smooth but have a gap at the seal where fluid will constantly drip then grease will form a good enough seal to drive it for a while. I am only talking 1000 miles or so. But you will still need a new slip yoke. The grease will sit in that concave part of the seal and keep in the atf for a while assuming it isn't horrible. If it was that bad right now though I don't think we would be talking about this.

I remember somewhere on this site that they had an issue with an actual hole in the slip yoke that allowed fluid to seep out. Might want to check that and see if thats it.

The grease seems like a waste of time to me. Not knocking you or anything. But if its at the point of having to add a thick lube to try and stall a leak, just replace it.

Yeah, but if you need to replace the slip yoke on a daily driver it can make life easier while you get the time/parts.

Well, I guess I should start in small increments.
It would be nicer if it was just the yoke, because a whole rear driveshaft would suck.
