x-fer case speedo leak

[71 Blazer]

my transfer case is leaking at the speedometer. I went to GM for a new seal. I put it in just like the old on it still leaked. Where on that shaft does the seal go? All the way back? I asked the GM guys but they didn't have any books on trucks that old. Am I missing a piece? All I have is a shaft with a gear on it, a seal and the nut piece that screws into the transfer case.

Does that mean that I have to buy a new sleeve, or can I just get a new gasket?

Not sure if you can get just the gasket.I believe it's more than just a O-ring.

I'm going to go to GM tomorrow and see what they can do for me. The part number to the sleeve should help. Thanks

I went to GM today and no one in my area has one in stock and its a special order. Does anyone know for certain that when you order the sleeve it comes with a seal? I just want to find out for sure before I order an item I can not return.

It's all one piece.
You get the steel sleeve with the seal allready installed.
That's how it came when I ordered mine anyway.

Thanks a lot. That would explain why mine leaks. I think the PO just put some sort of seal in there.

Thanks everyone for your help, I got that piece in the mail today and it is exactly what I needed.

Sometimes even my "simple tech writeup" seems to be the most appreciated!!

It took me a long time to find that part, so I'm always glad when someone else can solve the same problem SO much more easily!!

If you need "tech" on how to remove the ignition tumbler and trim ring.....let me know, I've got that one perfected also.

I used Greg72's write-up as well. I had to order the part. At first I thought that this sleeve didn't fix the problem because it still leaked for two days after installing it. I found out that there was a lot of oil in the speedometer cable and the tiny gearbox and it was draining out. So you might want to clean those out and grease them properly
