OS Giken diff question

[fryzia23]

This Saturday I'm going to install os Giken diff. I have all the extra parts but have a question. When reinstalling stub axles does the original c-clip stays on the shaft or does it get removed? I noticed there are c-clips already inside the diff. I'm pretty sure it needs to be removed but just want to make sure. Here's the picture of the c-clip.

So I ran into a major issue. When test fitting I inserted the sub axle shaft into the diff without much of a tap of a rubber mallet. Taking the axle out was a whole another story. It was pretty much impossible to take it out. Long story short In desperation I used a press and it came out but the axle stub broke off at the tip right after the c-clip groove. I My understanding is the c-clip that came in inside the diff is too thick for the factory axle stub c-clip groove so it won't compress properly upon removal. I was able to source a new axle stub which will be here tomorrow. I will take out c-clips from the os Giken and try it with factory c-clips. My worry is in the future if I ever need to take it out again. Here the pic of axle stub.
