If you have pretty good mechanical skills, I would take it apart and see if anything is loose or not where it's supposed to be.

it could be the WP,it has a shaft inside it,but first is it heating,dripeing collent on ground at right front tire.could be a bad knock sensor.if it were a wrist pin or bearing,it would not be intermittent,it would knock all the time.
