Trying to locate a little clunk sound from the rear and looking for advice

[Jasper7821]

I recently bought a 2001 986 S (100k miles) and the prior owner thought maybe it was a rear strut. he tried for a while to locate it but could not.
It sounds like it's coming from the right rear, I thought maybe it was the strut but not sure. It's not a real heavy clunk like a worn strut, but more like a heavy tap sound.
When I hit a little bump I can hear a clunk, But going over a speed bump I cannot hear it.
If I drive over a cobblestone road I can hear it even when going slow as the tire goes over each stone.
Doesn't matter if it's in gear or neutral, the sound is the same.
If I push on the rear of the car it doesn't do it.

Just curious if there's some obvious things to look for.
