Cv axle splines destroyed at the tip

[o. l. t.]

Okay so this is what my CV axle looks like. Do you guys think that I've got more damage in the diff or that I can just replace this axle and everything be fine? basically I'd like for people who have had experience with their diff to look at the damage on the tip of this axle and see if they think something deeper is wrong. I understand that this is asking for statistical information without inspection. Just want experienced persons to see if this looks familiar.

When I turn the wheel a specific direction it pops and grinds as well I lose drive and it as if it's in neutral. I was blaming the cv, but perhaps that's not it. Possible front driveshaft issues since I know the splines are boogered up going into the transfer case. Anyone have issues with their x5 having a neutral effect when having front driveshaft issues?
