So much for no leaks.

I drove the truck hard for over 100 miles the other day. Far more than I have driven it since I bought it.
The NP205 transfer case weep is now a full on leak. A big one.

I have UV dye and a UV flashlight coming on Wednesday that I'm going to use before I start wrenching.
Hopefully just output shaft seals however I foresee this turning into removal and a full rebuild.

Most of the time it is in fact the output shaft seals. The front one on my 203 is leaking like a stuffed pig lol

I removed the transfer case today.
The final inch happened a bit faster than I would have liked.
For sure I will be renting or buying a transmission jack to reinstall it.

That thing is disgustingly dirty and gross lol definitely a good thing that you pulled it out.

[BBM3]

There is at least a 1/4 inch of dirt on the top most of which is just a bit softer than 40 year old concrete.

I didn't pull it out as much as dropped it out. Thankfully the only damage was to the speedometer reducer and my ego.
It's not going back in without a helper, transmission jack, and tie down straps.

I found similar concrete type dirt on my crossmember when I had the engine out of mine. I also almost dropped a torque converter on my feet when I was pulling the TH350 out when I was swapping to the 4L60. Those kinda things have a way of getting your attention in about 0.002 seconds haha.

This is better.
Ready for a fresh coat of paint and reassembly. I can't decide on color. Chevy orange, gloss black, or other?

Black or Dark Gray.

Also I wouldn't be putting that back together without a twin stick setup.

Tremclad hammertone. The stuff looks really sharp when done properly.

I'd say Yea either matte black or grey, if it was me I would either do just medium grey or aluminum grey.

Did you clean that TC in your parts washer? It looks really nice. Ready for paint. I am going to have to take mine out and go through it someday. I am sure it could use a good rebuild.

Thanks for the suggestions everyone.
I decided to go semi-gloss black since I already have 2 cans.

I use this paint on shotgun receivers I convert and it has proven to be really tough.

I seriously considered a twin stick but I don't think I'll use it enough to justify the cost.

Yes I used my HF parts washer with full strength Purple Power in the tub.
I did find the Purple Power oxidizes aluminum pretty quickly. Not a good idea to soak aluminum in the stuff.

I was surprised to find no real wear in my TC only a little on the shift forks. Even the yokes have virtually no seal wear and the new improved seals touch the yokes in a different place.

Hope I can remember how to put it back together.

Hope I can remember how to put it back together.

There is a REALLY good set of videos on youtube about the 205 assembly if you get stuck. Looks good though.
