I have this clack coming from the drivers side front end. Its was getting progressively louder over the last few weeks but seemed to have plateaued recently. Seems to disappear when I brake. Pads and calipers are new. Thought the sound might have been related to dry cv. Got the fill plug free and the swivel seemed pretty empty so i filled it up with 80/90 gear oil. Still clacks. The sound is somewhat rhythmic but doesn't seem to correspond with every complete rotation of the tire, like you'd expect if there were a stone stuck in your tread. Any help on this one would be appreciated.
