Noise when turning left
 

I have 1984 Gmc High Sierra 4x4 with 305 auto. I noticed that when I turn the truck to the left. it has started making a kind of grunting noise. It does have power steering and I can sit and turn wheel fully to left and to the right when sitting running and it does not make this noise. I also noticed that it does this worse when I hit brake while turning it sometime sounding like metal on metal. I checked and greased front end and all looks tight and fine. The brakes are fine and just put brakes on it about 2 months ago and it has disk brakes front and drums rear. Any idea what I need to check?

Did you use some of that blue brake quiet glue no the pad's when you replaced them?

and is that little clip ok that holds the inner pad in the caliper?
