First, yes we have issues with the t/cases. The "dreaded hole" that they are talking about is the fluid pump wears thru the aluminum of the rear case half. If that is the case there will be alot of fluid coming from higher up than the output seal that you think is leaking. If you look hard enough on here there are multiple threads on this subject.
The output seal is also a common leak point. Just remove the driveshaft and pop the seal out and install a new one, be sure that the vent hole of the seal is pointing down.
Also repeat seal failures and leaks are usually due to a worn rear output bushing inside the case.

Yes, its a very common problem and it will affect every case that is known to have issues. Its a design flaw unless its fixed.

Yeah that is completely correct County Boy..
It is alot easier to take the case apart and install the updated pump clip and fix it for sure before you ruin the case

Well, as you all said, the seal was cake-work to change. However, the seal that I pulled out appear to be in good shape, no noticeable cuts or nicks. DS yoke also looked good.
This makes me nervous because I chucked the driveshaft a couple of months ago (the slip yoke snapped where it holds the u-joint).
The leak is no higher than the seal, because there is 0 fluid anywhere above the seal.
We'll see how this goes, hopefully this was the problem... the only thing that I did notice on the seal was there was some sediment on it... but that could have come from the case when I pulled it out.

And if this is a huge disaster waiting to happen, let me know, I've never cracked one of these open and I've never looked into any kind of schematics for how everything is laid out in them... perhaps I should buy a chilton or something...
