My old 745 did the same-it's the driveshaft centre support bearing or the rubber carrier that it sits in. When the car is loaded, the rear axle sits higher against the body of the car, which changes the operational angle of the driveshaft, moving it also closer to the body of the car. If the DCSB is gone, the whole assembly isn't sufficiently supported and will generate a clunking/thumping sound.
In my experience, this is worse in first gear and worse going uphill.
It's a relatively simple repair but made much easier if you can get the car in the air.
