I had a spring pop out when I was cleaning my 3/8 3/4 and was given these guys when I got my car with the parts. I'm pretty sure they are the outer axle seals but am not quite sure how they go in and my seal puller I bought it having a hard time getting the other ones out.

I could probably use more force, I just am always worried about breaking **** when I take it apart without knowing how to actually do it... Maybe breaking it is how you learn...:rofl: Or asking the geniuses on FABO always seems to work as well . :thumbsup:

Looking like you pretty much got it figured out.
That inner seal stops at a ridge in the tube that isn't quite a positive stop because it is tapered some, so slow and easy with the correct size driver gets those.

A little RTV around the inside of the tube where the seal bottoms is good, and I use my finger to spread a light film in there. (be careful of burrs or sharp edges)

I knocked the old seals out with a section of tubing and from inside the pumpkin.
Just set it inside the tube and reached it and smacked it.
(or a long section all the way through would work just as well.)

Just did a 8.75 recently.:D

So that rubber piece is not needed and will be replaced by the new seal? Is there a correct way these 2 seals go together?

I have a pipe that may work, well it's the handle to my jack lol .

If you are asking about the all black rubber coated seal in the housing in your pics then yes, it gets replaced by the green coated metal ones.
That's why I said a bit of RTV where they seat.
The all black seals are rubber coated so they seal good on their own.

The plain metal thinner seals go just in the retainer plate, and both go in with the open side of the seal facing in.

This might help with some of the visual details.

I like that. I see where it says I don't need those if I went with green bearings? So take the old ones out and don't install the new ones or do like it says and bteer safe than sorry?

My understanding is that the green bearings have their own seals built in.
I would still lightly RTV where they seat to the tube.
I have read where the inner seals can be put in for extra leak protection but not mandatory either way.

Well I tried to install the new seals my largest socket is a 36 which was a little small and bent the seal so that's a no go for me. I'm going to put it all in without a seal (unless I manically find one before I get it all hooked up and hope for no leaks.

On a side note a Copenhagen can is the perfect size to out them in but it is to flimsy to actually get the job done .

That's what I meant by "try to stay on the outside edges of the seal"

I tried but noting was big enough to fit the outer edges nicely. I'm sure I'll have to get something from. The auto store before I install it and I'll see about grabbing some more.
 
I hope you are more careful with my teeth. lol
long and short sections of various size pipe work great for installing internal seals and such

Teeth are much easier to work on, especially when I've done the procedures before. Here's some teeth I made after doing the root canals

I heard the pipe comments and sockets of larger sizes I just didn't have one so I tried without.
