Cv shaft house will not sit flush

Hey i replaced my cv shaft and realized it is not sitting flush. It has about a half inch of play. I believe its just the housing and not the shaft.
I hammered it on the lip pretty dam hard many times and it isn't going in any farther.
Any ideas of what could be wrong would be greatly appreciated.
The 1st pictured is of it pulled out the next is of it pushed in.

 

Normal

As long as clip is engaged you’re fine

 

It seems like its in there l, i live on a dirt road though. So i worry it will fill with dirt. I also worry the differential fluid will leak out. If not sealed. Also it was shaking like crazy on the highway going over 60mph.

 

Mine looks the same and I have changed a lot of cv axles. If you put it in 4wd does the vibrations stop? If it’s not leaking now then it is fine. My truck sees a lot of dirt.

 

Ill try to put in 4wd and see next time i can get above 60mph. I just redid the front end and had an alignment done. Thought I'd be good to go.

 

There was a similar thread a little while ago and it turned out to be two dust rings. I'll see if I can find it

Looks like that one had a squeal as well.

 

I searched around but couldn't find one that matched. Except people saying the length is wrong but it matches the old, so i don't think that's it. I am almost positive the old dust shield came out.
