This might be a bit remedial but I've never actually had a CV joint apart before. I just disassembled one of the Lobros in my sportsracer and the balls look like they might have some very mild pitting. However they feel smooth when you rub them with a finger tip.
Don't know how long these CV's have been in use but they are all dated 1998.
If you have a moment and some expertise, please take a look at the photo and offer an opinion.
Thanks,
Jim
