I was told that constant-velocity joints start making noise when the
car tunrs; when the wear increases they make noise even when the car
runs straight.

Could you give tips that allow to detect which one of these is worn?

Thank you very much in advance.

They usually fail when the boots fail. So check the boots every time you
change the oil.

The noise is usually a clicking on turns, bumps, anything that causes the
joint to flex.

to test the joints:

Outer: Try to move the axle on its axis, in and out of the joint, Free
play should be minimal.

Inner joint: Is designed to go in and out so the only test would be to
try moving it up and down. Make sure you differentiate between the play
inside the joint and the play between the joint and the differential.

Normally the noise would be enough to tell you which side and which one
is defective.
