I have been chasing this issue for 18 months. When I turn right I get a clicking noise from the front left wheel/hub area. I have changed the half shaft and then the hub, nothing same noise. I have 100k on the vehicle at 2004 4WD 2500 Suburban with a 6.0L.

 

Hub bearings or your brake pads may be loose. Lift it up and shake in a horizontal fashion to see if there is any end play. But likely hub bearings second would be brake pads jiggling.

 

When I changed the hub the bearings were part of the replacement unit. I did try the end play, none. I will check the pads. The noise increases with intensity and frequency a the more I turn the wheel. if zero is straight and 40 degrees is full right the noise starts at about 15 degrees.

 

I'd guess a u-joint or CV if that's the symptom.

 

Have you tried rotating the tires to make sure its not a nail or screw that is making hard contact with the pavement when turning?
Just a thought...

 

when I replaced the half shaft the CV joints are included. I have pulled the tires and inspected them. I have been considering a suspension issue that maybe on the rack can find. Thanks for the replies, I think it is time to let a shop look at it.

 

My bet.....im only gonna bet .02


Its your brake pads slapping around

 

well I fixed it. One of two things. Dust shield was slightly bent towards the rotor so I straightened it. Second lubed the caliper pins. Noise gone.

 

Great news
