ok seriously now, i need help. my beloved has developed a rattle an a clankin from beneath that i can't quite pin point. at low revs in a gear too high, so engine labouring, there is a noise coming from below that can only be described as "a trolly load of tea cups and saucers and tea spoons going along a rough surface". ok thats as best as i can describe it. its a metalicy clattery crocery kind of rattle. any ideas before i get slapped on the face with a land rover service and inspection bill?
