That's not a busted CV, those are just leaking CV boots. And that's just what happens to the stock CV axles after they sit for about a decade at one position and then their angle suddenly changes from the new lift. There are lots of threads on this if you search. You can try hose clamps to see if they will stop it from leaking, but ultimately you'll probably need to replace them (but not for a while). Once you replace them, keep these in the truck for spares if you 4wheel because CVs do actually snap and break fairly easily.
After my stock CVs leaked all the grease out and the boots had all torn completely off, I still drove the truck for several months, through a snowy winter with bare CVs on both sides.
