04 kodiak

Hey all,
New to the site. Never did this before. Felt like I was joining a cult just signing up. Anyway, here’s why I did.
My 04 Kodiak just quit moving. After much digging, I found that the ring gear is slipping on the axle. I find it hard to believe that the splines would just strip. Anyone ever heard of this happenening? I don’t know if I need to find a new axle, a new ring gear, or both? Anyone have any input?
