Front end noise?

I have a bit a of a problem. I have a clunking noise while turning. I have double checked all U-joints, rod ends, ball joints and bearings. I found a bad track bar bushing and replaced it. I didn't make a difference.. Could it be in the dif?

mine did the same thing and it was the bracket on the frame for the trac bar. The bolts that come through the wheel well where just a tad bit loose.
