There's a clicking noise coming from the wheel well when the truck is in motion. Is it possibily the CV joints?

does it only click when you turn? if so that is probably it. i do know of one case though that they made noise in any condition.

no, it only clicks when going highway speeds.

My 2000 has rubber flap-like things inside the front wheel wells covering some holes leading to the engine compartment. They're held in by those infamous plastic expansion clips. Well, a couple of the clips came out, and the rubber starting flapping with the breeze. It was noticeable as a noise at a certain speed.
So, check out all of the rubber and plastic trim inside the wheel well to rule that out as a possible source of the noise.

well then I don't know. I guess try the the rubber flaps like toto said. just get under the truck and check for anything that is loose.
