    when reversing i get a knocking noise from the front end sounds like from gthe gearbox but dont know if a new gearbox is required or if something else does. i have had all engine mounts changed thinking it could have been one of these that had gone but the knock persists. i have no problems in any other gear but reverse any help would be great.
