I just noticed that the front spindle has popped out of the front differential on my 06 Rubicon. I don’t know how long it was driven like this but likely not in 4 wheel drive.
What do I need to look at for repair? Can I fix this myself? Does it need to be replaced?
Thank you for any guidance?

mods, I accidentally posted this in brakes and suspension but I think it may need to go here. I did not mean to over post. Please delete which ever one is out of line.
