Rattling noise from another vectra

Hi!
When driving my Vectra-99 hatchback on bumpy roads, there is a rattling
noise somewhere in the rear end. I have checked for loose objects, exhaust
++, and i still havent found anything wich could explain the noise.

Another article here mentions roll bar bushes, springs etc.

I have heard that the "Inner roof " may be loose. Anyone who can explain
what this inner roof is, and how it can be fixed?

Thanx

You can easily tell when the inner roof support bars come loose. Sit in the
car and shut the door quite hard - it rattles above your head if the bars
are loose.
