My gasket kit for my np205 came will all new seals as well. I don’t think I have a good way to press the new seals in so my question is should I replace the seals or not? My original plan was just to replace all the gaskets but I don’t want to have a leaky transfer case because of a bad seal. Thanks in advance.

The seals dont need a press. A tap with a hammer and a block or something is just fine.
And yes you definitely should replace the seals.

Ok follow up question, does this require taking the entire transfer case apart or not? I know I can I just would rather not if I don’t have to, when I say take it apart I mean down to the bare housing.
Check it out and decide what you want to replace...

It is not an entire disassembly even for the shift rail seals but it is almost all the way bare. You just leave the idler gear assembly installed.
It's a very simple tcase to reseal but it was daunting for my first one. I've done probably just shy of 30 now and the second one was just as easy as the last.

Thanks for this, it will certainly come in handy if I decide to tear the whole thing apart, which at the moment I’m leaning towards.
I’ll be keeping you in mind when I inevitability mess something up and need guidance lol. Thanks man.
1st transfer case I ever rebuilt was a np205. Complete success with no problems. As long as you have a good manual or some instructions it isn't very hard. If you don't feel it needs a full rebuild a reseal of the outputs is even easier.
I used this video series with a tablet on the bench with me. Step by step.
So funny I was watching through those videos last night in preparation for potentially tearing mine down, great series and really helpful.
He does the sm465 too. It also worked well for me to follow along and rebuild mine.
Yep watched it when I did mine
My first was a 203, and I had no help, it was in the 90's and it was the worst puzzle I had to do.
I even had to cut my own gaskets and find seals by bringing the original in.
After putting it together successfully, I tackled the first th350 rebuild.
Anyone know exactly what this is and how to get it off?
I thought it was a vent but it’s closed off. The tube was attached. it just looks like a metal stud with a lip to hold the hose on. Anyway it’s preventing me from taking the bolt out as you can see, any ideas? Thanks.

It is a vent. Take the rest of the bolts out, smack the housing with a mallet. This should separate the gasket and allow you to pry up the housing a bit to get the bolt out the rest of the way while removing the housing.
Just looked at mine, must be a difference in different years. My vent is in between 2 bolts, not over the bolt like yours.
It is a vent and you can see the dirt plugging it.
First time I see it on top of a bolt.
This plugged could cause the seals to leak.
Open up the hole, it is not big but it makes a difference
There are different variants of rear output housings with speedometer and vent outlets.
While it's out, tap it for npt and put a barb fitting. Tap the shift rail detent bars and roll pin access holes too.

Good idea, will do thanks
Cool, yeah seems like a bad place for it. I’m replacing all seals and gaskets. I’ll try to clean it out.
