Mazda 3 "clunk" from the rear

[samanto]

Hi guys i own a 2005 Mazda 3 with 120 000 km and since a few months, i keep hearing a dull "clunk" whenever i hit a bump or turn at low speeds. I have recorded sounds from my trunk while i was driving and we can clearly hear the clunk mutliple times. Does anybody have an idea for what could cause this problem? I have already checked the stabilizer bar nuts and everything is tightened and unmovable due to rust.

Thank you

(Listen to the recording with hearphones preferably)

Oh, at the begining, I am only testing the microphone ^^

Wrong forum. Might have better luck over there.
