Hi,
Thank you for your reply, the lower suspension arm was damaged so was replaced. But with a second hand part as I needed it back on the road ASAP to get to work. My mechanic seems to think there are only two points that could be effecting the wheel. I am off to get a second opinion tomorrow but it is very weird! And worrying as it is not obvious where it is coming from! It has been on the ramp a few times with different eyes looking each time!
