Axle not staying in rear diff

[WRXONP]

So I snapped my passenger side axle inside The diff - pulled it all apart and got the broken piece out - so to get the passenger side broken piece out I removed the driver side axle and pushed it through -

When I pulled the drivers side apart / the axle just came out - didn't have to un clip it or anything

Upon re installation - I can push the cv hard up to the diff and it doesn't clip in - the clips in the diff how ever

Is it the wrong axle ?

The end of the driver side axle steps down ? The spline gets a lot smaller and there's nothing inside the diff for it to engage to because the spline is all the same diameter in the diff ?

I can get pics but any help is appreciated I need my car going again

I have faint memories of having a similar issue where one type of diff held the axle in place by the clip just passing right through the spline and locking against the inner face. So the clip had to be right near the end of the axle and the make spline obviously longer than the female spline.

Then there were others that had the clip further down the axle which lock into a groove within the female spline.

But it's been years since I've been near a rear diff so I may be wrong. Hopefully someone else has mixed and matched bits more recently.

Hows the other side look, have you taken that apart to see if there is anything you could be missing,?

What u mean ?

The passenger side snapped - I removed tw broken part

It broke at the recess for the clip (weakest part cos it's the skinniet)

The other side looks a lot different where it goes into the diff - the clip is in the diff and without measuring it - it looks like it's actually the correct depth to clip in

Figured it ! And FML it's the same problem I had a few years back with my old suby - even a old thread about it too

After getting axles from the wreckers today and discovering that the left clips in and the right still doesn't clip in - I thought **** it and pulled the diff out to sort this out on the bench - pulled the rear casing off and I have a ap suretrac diff

After a brain fart I tried the left axle on the right hand side and wallah clipped in

Done some internet searching on ap suretrac and it says they use 2x left axles

Back to the wreckers tomorow to get 2 left axles haha
