Creeking noise - front end

[tbuckley]

The left-front end of my rig seems to be "creeking" or "kinda grinding" when I turn to the right and occasionally to the left. It sounds worse when I turn to the right with the front left carrying more weight -- i.e. coming down a hill and turning right.

Could it be a bearing? Loose bolts? My H2 has a 4" lift, dual shock hoops up front and I'm running 38" x 13.50" Toyos. I know the above is vague, but does anyone have an idea of what it could be??? I did check for any small woodland creatures hiding under there... none found.
Any help would be appreciated -- thanks all!

I noticed in my 'search' of the site that there have been some discussions about a similar sounding problem, but no answer to the sound or fix.
