A while back i destroyed my brakes and had to remove my locker in order to replace the backing plate. I ended up buying a new axle cuz i couldn't get the locker out. I would try different ideas in my spare time. Today i had a idea that finally worked.
To all those in future that need to remove c-clip from the locker the trick is to get some fishing line under it. Then you can pull it out just fine. Basically rotate the axle shaft until you can see both ends of the c-clip through the slot in the locker. Then take a loop of fishing line and a straight pick to push the fishing line under the c-clip. Then rotate the axle shaft while sliding the line under c-clip. Once at the opposite side of the shaft just pull it out and hope the line don't break.
Hope this helps somebody. It was really easy to do and i got in the first try. Now i won't be so nervous about putting in my current axle.
