Help--> Rubbing/grinding sound when turning

[bluesilverz71]

I have a 2002 Silverado 4x4 that recently started to make a rubbing sound about 2 months ago now it’s almost to a point where it sounds like something’s grinding when making right turns at any speed. I thought it may be the tie rod, got under the truck and the tie rods still very intact. Also thought it may be the steering bracket (linkage) but nothing seems loose.

I am usually pretty competent with repairing cars but the trucks got me scratching my head...

 

Anyone have similar experience? Or have an idea what is causing this?

 

Any input is apreciated..

first guess would be hub bearing
