i thought my throw-out bearing was going out necause when i had my foot in the cluth it wouldnt rattle, but in nuetral with my foot out of the clutch it rattled like crazy, so i suspected the throw-out bearing. took it to the dealership and they replaced the clutch. it still does it, is it just the gears making all the racket? should i add some lucas when i change fulids? any input would be greatly appreciated
