Have you checked
(1) the condition of the lower strut mount condition (is it broken or cracked)
(2) the condition of the control arm busing (is it broken or cracked)
I have a similar problem and the strunt mount bushing has one crack line. But its definetly not worn out. I get some metal grinding sound when ever I steer to make a left turn. This sound is from somewhere on the front right wheel area. Previously for this problem I was told to replace the inner tie rod end and I did and it was fine. But its started again now. Its hardly been 10,000 - 15,000 Km.
