The right front is ratteling on my 518 -96 (e34). This happens when I run over bumps and the ratteling is becoming extra loud when braking at the same time as going over bumps. I've looked at it and there are a lot of arms and therefore hard to tell where it comes from. I try to shake the arms but they seems to be firmly fastened. I'm probably too weak to produce the rattle artificially. What is the most common fault where rattle can emerge?
