Front end noise

I have a '01 cherokee limited, and there is a noise coming from the front end when i hit small bumps in the road, like the reflectors on the centerlane. It sounds like it is very lite, and could be related to something in the suspension. I just had it aligned and tire rotation and balance and the noise is still there. Not sure what it could be? thought I might try a forum to see if anyone has related problems or fixes.

Try having a buddy turn the steering wheel from side to side while you look underneath at the front suspension. Pay particular attention to the joints (tie rod ends, track bar mounts etc...) The problem on mine was the tie rod end that connects the pitman arm to the drag link.
