The coolant overflow system did its work.

Your radiator may be plugged up, or your water pump may not be working

air well enough and the system is overheating.

A quick look inside the radiator will tell you if the radiator is
getting plugged up with gunk and needs replaced or not.

CV joint is bad. No big deal. Buy a rebuilt axle and be done with it.
