Replacing transfer case front output seal?
My transfer case is leaking at the front output shaft. So, looking through a bunch of old threads I matched my problem to the pics that urn.frosh posted a while back. It turns out that his problem was the output shaft seal.
Anybody know *how* to replace that seal? I only have a good set of basic tools (sockets, wreches, etc..). I've gone over the instructions in a cheapy online manual, and it didn't make any sense to me. "Remove _____" is pretty vague.
If anybody has an idea, I'd greatly appreciate it.
Oh...there's a crap-ton of 2nd gen xfer case problems in the 3rd gen/taco forums...

Involves dropping the transmission. You up to that? Depending on your mileage, good time to do clutch service as well (if 5spd).
I browsed around on Pirate looking for a how-to, but didn't get anything specific. Didn't spend a lot of time though.

What?! Drop the transmission to replace the output seal? Ouch.
We are talking about the seal at the front driveshaft, yes?
Edit: Even the FSM is vague.

No need to drop the tranny to replace the front tcase seal. My FSM is also vague, but it basically says to unstake the nut, remove it, pull out the flange and seal and replace seal and flange. The torque for the nut is 91 ft lb, and it should be restaked. That's for a 2nd gen but I would expect the 3rd to be very similar.

Front output seal. Meaning front driveshaft?
Remove the driveshaft,companion flange, seal/bearing retainer, knock out the seal, drive in a new one, scrape old gasket material from both T-case housing, and seal/bearing retainer, install new gasket, seal retainer, companion flange, driveshaft, done.
edit:
Don't forget top top off the T-case fluid when done.
The companion flange may need a "speedi sleeve" if it is grooved/worn by the old seal riding on it.

The companion flange is what the driveshaft bolts up to.
A speedy sleeve is used when a groove is worn into the companion flange "nose" [ internal cannot be seen until it's apart ] that rides on the seal.
