I have a funny clicking noise that sounds like it's coming from the front passenger side of my truck. I have a 2000 F-150 4x4 off-road. I always let it warm up for a minute or two before I start driving but here recently this noise has come about. It doesn't make the noise when stitting in park at idle or in gear at adle for that matter. But when I start rolling (even with no throttle applied) it starts this clicking and it gets louder and faster the faster I go. It goes away after a few seconds and then all is well. It only does it after it's been sitting for several hours. I've checked all fluids and oils. Any ideas?

 

I had a similar problem and believe it or not, it was a wheel that 3 out of 5 of the lug nuts had gotten loose. I drove down a washboard dirtroad for several miles and it came loose. I'm lucky I didn't loose my wheel. I heard it also when I applied my brakes. it would tick each time the wheel made a revolution.

I know it is simple but just make sure all your lug nuts are tightened.
