Yeah I didn’t see it in the diagrams also.
I uploaded a link to a pic with an arrow showing the spot where the second snap ring is on. This isn’t a pic of my vehicle personally.
But basically about an inch further behind the first snap ring and directly in front of the round lock nut for the wheel bearing if that makes sense. I’m not sure if it’s supposed to be there. My dad changed the cv axles a long time ago and I did them again about two years ago after it was making some noise. When I went in there the second snap ring was there and he said he put them in as the axle had a second groove for one. I guess he thought one was supposed to be there too.
I haven’t had problems with it there but I saw a YouTube video where an individual had a manual hub damage due to the snap ring being installed on that same position where I also have one.
I guess I can simply remove it since it’s not in the diagrams. Even in the manual for replacement of the axle it doesn’t mention a second snap ring.

By the way, how are the manual hubs? Notice any improvements in steering or fuel economy?
