Electrolux RM2260 Fridge Problem with door

i ,Can anybody give me advise on how to solve a problem with my fridge door ? The door is supported by a lug top and bottom ,both lugs have a pivot that fits into the door top and bottom. All very simple But the door keeps bouncing of the hinges when in transit.  I know the fridge is 20 years old but it works well but the door keeps jumping of its mounting.I am off to France in a couple of weeks so there is no pressure !!
