Wheels chirp when turning

I have a 2003 chevy s10 zr2. I recently replaced most of my front suspension components excluding the shocks. My front wheels have a negative camber that I can't seem to get rid of. Just yesterday I snapped my pitman arm and replaced it. But now whenever I turn, the front wheels make a chirping sound as if they are losing traction. Truck is 4x4 but it's been in 2wd. Granted the front tires are worn horribly now because of the camber but I wouldn't expect this to cause such problems. Any help to point me in the right direction is greatly appreciated!
