2004~2008 Mazda3 Clunk when accelerating from stop and slowing down

[hgpham]

Hi, I have a Mazda3 2008 2.3L AT and everytime I accelerate from a stop, I get this sort of clunk that is driving me crazy. This also happens when I slow down from speed as well. Here is a video of what it sounds like.

A point to any direction is appreciated.
