2005 GMC Sierra Clicking noise nobody knows

IF there was not a bi-directional surface put on the rotors, it will be much like an LP...vinyl record. The pads can act like the needle and follow the grooves until the pad clicks back in place.
Although the pads should not be touching the rotors while driving, it doesn't mean they are not.

Try running the truck up on a lift and use a stethescope to locate the noise asuming it will do it up in the air.

Were all these parts replaced to try to eliminate the noise? OR has it started afterwards?

Any changes if you are in a hard turn regarding the clicking?

The parts were replaced trying to eliminate the noise. I believe the resurface was bi-directional. The truck was run up on a lift and the noise goes away. The clicking only comes in with load on it. The CV shaft and hub were recommendations from a repair shop. Turning does not seem to effect the noise speed does, the frequency increases with speed.

Mmmmmm....I hate to miss diagnose...I would have thought both the bearing/hub assy or driveshaft at first thought myself.

Other things that follow RPM could be the flywheel, (cracked).

Might be worth picking up some chassis ears.
Since it only happens under road conditions, this may be the only way of actually testing that I can see.

I finally have success, the same repair shop I started with found the problem. The tire shop I had used to put new wheels and tires on left wheel weights loose. The wheel weights were attached with double sided tape and two of them would rattle with slight bumps in pavement. This was a very expensive lesson in always start at the beginning. Each shop skipped the simple because i had told them what has been checked, oh well. Thanks!!!!!!

So easy to overlook the basics. That was why I asked about the sequence of events. Glad you got er!
