I have a 2012 Elddis Avante 564 and have just travelled back from south France.  Shortly after setting off I noticed quite a violent 'kick' coming from the caravan during stopping and pulling away again - I assumed just possibly my driving causing it!  However
when I stopped at a service area and checked the hitch, it was apparent that there was oil sprayed all over the lower rear of the car and the underside of the hitch.  Am I right in thinking that this is hydraulic oil from the damper in the hitch that has failed?
 Is this a repair job or a new hitch?  Any comment appreciated.  Thanks.
