Get under the car while it's jacked up and try rotating the wheels back and forth with the car in gear while watching to see how much play is between the axle and the flange the CV is bolted to. There has to be a little and with experience you can judge how worn the balls and slots or grooves they run in may be worn.

While driving, if you hear a click when starting to move after going the opposite direction or while turning then there is wear in the balls and grooves or a crack in the cage that locates the balls.

You have to take them apart and clean all the old moly grease in solvent and inspect the grooves, balls, and cage.
If the grooves are just polished and not worn deeply from movement of the balls then regrease them and put them back on the car

They don't last forever with a powerful motor so you have to be the judge on how much longer you want to put up with the slop in them or spend the money on tight new ones.

I've seen the inner section or race of Lobro CV's break apart with a bang and shred the CV and axle splines on hot rodded 6 cylinder BMW's when accelerating hard with the car full of people..
