Clicking noise when turning steering wheel...

alrite well this seems like the most appropriate place to ask this question.....i have a clicking noise coming from my front end when i turn the steering wheel. noise comes mainly from driver side. also makes the clicking noise if my wheels hit the sidewalk when parking. i had a feeling its the cv joints going bad...so i took it to the dealership but they claimed that they didnt hear anything, and that it was fine! (yea right!) anyways...just wondering if the cv joints should be my main focus here before i start messing around with the truck myself???
thanks*
