I dont think i saw any cracks or tears in the cv boot. this could be bad or good.

 

I think some of the responses may be freaking you out a little. If the clicking can only be heard against a solid surface like a wall of a building & not when you're driving, the chances of it being a C.V. joint is 0% to 0%.

Honestly the likely cause is one of 2 things, first like some suggested, something stuck in the tire. It would only take one large screw, nail, or like object to be stuck in one tire to get that clicking sound. Second would be something with the front brakes, like the pads are getting worn out & the wear indicator is now JUST starting to touch, so you probably won't hear it under normal driving, but against a wall where the noise can rebound back at you.
If you hit the dealer for brake inspection, some will due it free or for a minimal cost, if there is work to be done, they will usually waive the inspection fee.

Good Luck!
