Yeah I have a look now everything is apart and access is easier. I've heard of the floor cracking and the left side gaurd cracking where the battery tray is. Its not going to hurt to look...

This sound is weird. In the car it sound like a knock, when I kick the tyre, it sound as something is lose. I kick the right side tyre, on the front of it, and you hear the noise, I kick the back of the tyre and you dont. Left side doesn't do it at all.
I might remove the battery while I'm here and look for any damage.
