I have a 2008 VE SV6 sedan, bought brand new, and just wondering if anyone else has heard a knock type noise coming from the passenger side doors when going over bumps or sometimes just turning a corner or accelerating? Basically I have Holden telling me that they cant find anything. I have a work car VE wagon same vintage which seems to have the same problem. Havent taken anything apart but there is a noticable difference in the sound when you open the left side doors as opposed to the right. Has basically done it since day one and now I am looking to sell it and would like to fix it as a potential buyer may think that it has been in a prang or something because of it!

My first post here so would be great to hear from anyone with some ideas...thanks
