The Dreaded Tailgate Rattle
There are several different causes for the tailgate rattle, and indeed describing it as a 'rattle' can be misleading. Some movement of the tailgate due to loose hinges can cause an irritating squeak as the rubber seals shift against the metal and glass. The best solution for this is regular applications of silicone polish, or even Preparation H pile ointment (so I'm told) to the rubber seal itself.
There are other sources of rattling that can be pinpointed inside the car itself. If the rear seats have been folded forward and not replaced properly, they will rattle and creak over bumps and twisty roads. Likewise anything stored in the two little cubbyholes in the boot may rattle and sound like a herd of irate elephants. Check also that the spare wheel and tools are all properly secured, and that the ski-hatch behind the rear seat central armrest is properly latched home.
More serious is the noise made by a flexing of the bodyshell due to poor or missing spot welds on the top crossmember above the hatchback opening. This is a recognised problem with pre-06 cars, and Alfa Romeo have an official fix for it. The rubber seal, rear trim and various other bits and bobs are removed, then two short bolts are fixed through the internal bodywork, rigidly clamping things together.
This is a fairly time-consuming procedure, and not something you should try at home, as the removed fabric headlining has to be glued back into place.
