2005 camry 2.4V

hi guys , newbie here, id like to ask what could be the cause of the clanking sound from the rear of my car , i cant identify it if it comes behind the rear seats ( note that i dont have anything on my trunk) or from the rear under suspension, it clanks when i drive on uneven surface but vanishes when im on smooth asphalt surface. any clues guys?

thanks for the advance info.. coz i dnt wanna spend money on something im not sure of first. id like to troubleshoot first.

thank you.

It may be your anti-sway bar bushings or links. Have someone bounce the car when your can see under it. May also be your strut mounts. See where there is up and down movement, even just a small amount.
