Golf IV / Jetta IV :: Front Tire Clicking Only Above 20mph - CV Joint?

Had to get a state inspection this month, and originally failed due to front right outer tie rod and both control arm bushings -- i bit the bullet and had the shop do this work for me, since I am going on vacation this week and i plan on using my car.

Anyhow, got the car back, and now i can hear a light clicking or tapping noise, but i can only really hear it when i put the window down, or if im driving by one of those concrete median dividers. Its as if someone is taking the metal tip of a screwdriver amd tapping it against a hollow metal bowl -- it makes a clicking noise, not a clunking or whirring noise...

I can only hear it when i hit 20mph; any less and i cant hear the clicks. At 20mph, its a slow, faint click that seems to be closely related to the wheel spinning. At 40mph, i can hear it is much faster, but just barely louder. I hear it best at abouf 25-30 mph, before road noises begin to over power the clicks.

Turning does not seem to affect the clicking, nor does braking. Its just constant -- if the wheel is spinning over 20mph, its clicking. Whether i coast or accelerate does not matter. I checked for rocks/nails in my treads, and with the exception of quite a few tiny rocks (which i took out), there doesn't seem to be anything remarkable. I checked my CV boots, and i cant find any signs of tearing or leaking grease...

If it is my CV Joint, wouldnt the mechanic that did my inspection, who caught my tie rod and control a bushings, and who did my alignment -- wouldnt he have also noticed something odd about my CV Joint, if something is indeed wrong?
