Right front wheel grinding, grateing noise, when i stop it clunks and sounds like it disengauges then works again for a little while, sounds like it trying to engage that wheel or something slipping, 4whl drive works fine
I agree with duane_wong on this one ( not like he was looking for my approval :) ), it sounds like a problem with the IWE ( Integrated Wheel End ) on that side.
Quick test, when you are in 4H ( or 4L ) does the noise still happen ?
I would say cracked vacuum line to the IWE, or a problem with the vacuum diaphragm in the IWE. You can test by having the motor running in park, and in 2H, and check the vacuum line at the IWE for vacuum. Make sure you test to the vacuum line, not the vent line ( ends in the engine compartment, not hooked to anything )

Could be the vacuum line to the IWE or the IWE solenoid.
There is a TSB on the 04-06 IWE solenoid, where it can ingest water and cause the vacuum not to hold, I would suspect both sides to have the problem if it was the Solenoid.
Start by testing the IWE vacuum line with a vacuum gauge, with the problem only being on one side, I would say vacuum line. You can unplug the vacuum line from both IWEs ( not the vent line ) and drive it with the front axle engaged as not to damage the IWE gears. IWE solenoid TSB :

The vacuum will be applied with the truck in 2H and the engine running ( vacuum holds the IWE gear out ).

Maybe the hub assembly and bearing are weaing out.Check other front end parts for play.
Hope this helps.

I drove a short distance in 4H & 4L no noise, only after driving in 2WHL for a little bit. some times it takes longer or shorter time for the noise to start again after I come to a complete stop an start driving again. I haven't been driving it because I didn't know if I'd cause more damage until I could fix it.
