When in 2wd drives fine lock in 4wd makes vicious clicking sound have changed inner and outer tie rods the manual locking hubs and idler arm still doing it any ideas

 

Best thing to do is get it up on jack stands lock the hubs and move things till you find what is loose.

I would look at the CV axles and Front drive shaft

 

I deleted your other thread on the same subject, please don't create multiple threads on the same subject

 

Oil in your front diff? Fluid in transfer case?

If both of those, then my guess would be CV axles over front driveshaft, as driveshaft should be more a chirping if just U joint going bad provided you haven't completely broken a U Joint -- if broken then U joint will click.
