Clack noise from the rear

[Akebono]

Hi, sometimes I hear a clear clack noise, like something snaps off from the rear side of the car. First I thought it was the driverseat rocking but that was not the case. Now I realy do not know if this is from inside the car or something on the body of the car. This happens mainly when accelerating the car from standing position pretty hard, so when the car is leaning back due to moderate-hard acceleration. After that "clack" it gets quiet again (cannot reproduce it) until the next situation like that. I susspect something regarding the rear-axle, like a bushing or a bolt holding the rear shock absorber. It's on the drivers side rear.

Maybe you know something about this. I've searched with no luck :(.
