Have a 2000 reg cab long bed z71 with a clicking\clunking type noise, I think it's coming from the front drivers side wheel area. It ONLY happens going from 0 to about 10 mph and the noise gets more rapped as I speed up, so I assume it's something rotating causing the noise. I have no idea what it is, i've lifted up the truck. all suspension and steering componets feel tight and good, I don't feel any vibration or anything in the steering while it's going on, just the noise. and also the 4 wheel drive works. everything else seems good. Any help is appericated.

 

Could possibly be the U-Joints in your front drive shaft.

 

Is your CVhalfshaft boot torn?
