Cv axles replacement

Hey everyone. Been lurking a long time and first time posting. I tried searching around but where I'm at right now it's REALLY hard to use Internet. So I apologize if the answer is right there.

I've got a 2017 OR and just noticed that my drivers CV has a nice tear in it and has been shooting grease all over. I just got to my families ranch after driving about 1000 miles. My current set up is a little under 3" of lift with TC UCAs, stock lowers and sitting on 285/70/17 with 17x9 wheels.

I honestly don't know how it tore like that. A month ago it was fine but in that time I did light offroading (fireroads) but did hit some debris that blew onto the road from who knows where. But as a once over things looked okay.

I was thinking maybe they are at too much of an angle from the suspension and just tore? Or more than likely something caught hold of it?

But now I ain't going anywhere until I replace it. Where can I get a replacement that isn't going to break the bank and is there a good "how to" for these 3rd gen? Hopefully these pics load. The other side is completely fine.
