Hi guys, I was a part of the site for years, but I can not remember my old username and made a new one, anyways I have a 2000 T/A ws6, when I am slowing down, or going around turns I can hear like a clicking sound, its louder when I have a person in the car with me, sounds like its coming from my rear end. Anyone got a clue as to what this might be? Thanks
