Just a shot in the dark,but does the noise go away when you touch the brake pedal slightly (just enough to engage the pads onto the rotors)? My FSJ has a clicking noise when I'm driving. I can't really hear it unless I'm driving next to something that will reflect the sound back at me. I figured out that if I barely pressed the brake pedal it would go away. I guess the anti-rattle clips must be missing. :dunno:
