I haven't heard any metal on metal sounds...it just sounded kinda like a spring snapping back into place or something...like a pop with a tiny echo sounding thing. It's really hard to explain, but it's happened on both sides in the front, at two different times...and its been the exact same thing: a fairly quick turn and brake. Any new ideas?

BTW...thanks for everyone's help so far...I'll check it out a little later.
