Before my cv's were replaced they were really bad, they make a knock knock sound when turning especially at full lock. Also powering on there was a clunk sound and slight delay getting the power down. The best thing about the new cv's is the steering feels tight when moving the steering wheel the car points better and is smooth and responsive.
You may be lucky and only one side needs doing for now.
My cv's made a sound turning both ways and both cv's were replaced.
Sounds like its time to hoist the car up and see what needs replacement.
Good luck,
was it new or did you just replace the boot??
didnt last vaery long at all so.. downer
