So my question is if anny one had this or heard this rear cracking sound, i would be thankfull to tell me the right location where it is, i have made a video from it so let's check it out if i can find some help here in this forum.

When does sound occur?
When pulling away from a standstill?
When accelerating whilst moving
When braking?
Turning Left? Right?

Try driving with windows open (radio off) to try and pinpoint if sound is at front / rear / left / right.

ps You didn’t attach video / link.
