92 940 shakes and rattles under hard acceleration

I have noticed that whenever I accelerate quickly my sorta shakes and groans and vibrates from the rear.

I topped off my differential fluid and changed my transmission fluid.

should I be concerned?

The car will give feedback on hard acceleration, your differential might be getting worn out, but probably will never give out. As for the shaking, how are all your bushings?

check the driveshaft center bearing too. its in a rubber waffle support, that hardens and cracks, then the drive shaft can rattle around under heavy load.

worn rear suspension bushings can do this, too.
