tl;dr new driver's side axle spewing fluid, are they not in all the way?
So I replaced my axles on my 93 nx2000 with o'reilly autoparts new axles, LSD and ABS version. They look pretty good, we'll see how quickly they fail, lifetime guarantee, should have gone raxles, yadayada.
Everything seemed good, but I had a funny feeling after I did the driver's side that it wasn't all the way in, then I thought it was, but I'm not 100% sure. Anyway, fastforward to driving it for a day, parked it after about 30 miles, came back to what looked like most of my MT-90 on the garage floor.
I didn't get new seals because the existing looked good, but showing the photo below, I don't think it's in all the way - why didn't it seat? do I just need to get on it with some pressure? whats the best way to get it to seat? I can I just BFH it from the outside (with the 32mm nut attached of course)?
it DID have a circlip on it when I started to insert it.
See pic, looks not in all the way, how do I get it in? (top is new axle, bottom is tranny):
what did I do

- it's a holy mess.
