CV shafts should be able to go very high mileages. My 1988 Forsa still has it's originals. The main issue with them is the rubber boots= if one has a tear- sand, salt or water can get in leading to premature failure. Keeping an eye on these is important.
during cold mornings turning right I have gotten clicking on both my AWD Autmatics - it is only when cold and not all the time - I was told by the dealer no worries - it is normal - no wear was seen and no problems - that was years ago
