CV AXLE PROBLEM. PLEASE HELP

[Thelittlekg]

Hey guys. I'm new here. But I have a 2006 Cooper s on full coils and ssr Vienna kreis 16xskinny. But I had a cv axle snap on me doing like 60. Brand new axle just replaced it a few days before. Since that happened I haven't had my car driving for 5 weeks. I've bought oem refurbished axles. Oem axles Oriley axles and autozone axles to see if any of them would work and they all do the same thing. I put the axle into the transmission and it seems to lock into place fine. But whenever I put it the knuckle and tighten the axle nut it pulls the axle out of the transmission.
I also have no bad motor mounts or transmission mounts and I'm completely stuck. Anyone have any idea where to go from here?

Either get the snap/lock ring from the OE axle, or one from MINI and swap it with the one on the aftermarket axle.
