Trying to get axle into transmission, turning out to not be as easy as it looks, don‘t want to break lock off into transmission, which is why I am having to replace it now.
There is a snap ring that rests in a groove in the splined axle stub that goes into the transmission. It has to be compressed during the insertion process. You can take it off and bend it a little smaller in order to make it easier. Also a little grease on it helps. Then make sure you have the axle aligned properly as you insert the stub. If is on an angle, it won't go in right. Then you can tap on the CV joint with a hammer and block of wood.
