Need Help With Clicking Sound from Tire

[tomy]

I have a bit of a problem with my '89 K5. Due to work and vacation I haven't driven my truck for about 6 weeks. When I got it out yesterday there was this loud clicking sound coming from the front of the truck. It got louder as a I sped up and when I stopped it was gone.
So far by jacking up the 4 corners of the truck and spinning the tires by hand, I have found that the clicking noise is coming from the driver's side front tire. I removed that tire just to be sure it wasn't the trim ring making the noise. When I spun the hub without the tire, the clicking noise was still there.
Does anyone have any ideas on the cause and fix for this problem?
Thanks in Advance

warped rotors can cause the pads to dance around inside the calipers. Check the run-out of the rotor.
Or you could have a wheel bearing out of adjustment

tomy, read my post about noise in front wheel. I just went thru similar problems.

Thanks for the help . Could it also be a problem with the auto hubs? How could I tell?
