43k miles, clicking sound from driveline when steering wheel cranked over to one on 2003 Mercedes-Benz S430 4MATIC

side or the othr. Possible a CV joint in the front driveline?

Asked by for the 2003 Mercedes-Benz S430 4MATIC
There are rubber boots on axles where the joints are located. Is one ripped on the side where the noise is coming from?
Just picked up the car last week. I'll take a look for a split boot.
