It's not the ball joints, and everything seems secure (checked all the suspension joints and nothing looks out of place) what on earth is it?

It was a very popular tyre depot just outside Winchester, which normally gives great customer service. Wondering if to take the wheel off tomorrow and have a look.

Only happens when you turn into the wheel, The weight knocks on the brake because it is too fat for the small space on the inside of the alloy, A flat glued weight is the right one not the wedge.

I can't see because I am tired, but it looks like it has been rubbing against something. Also, there is very little clearance between the damper casing and the edge of the wheel.

Took it back to tyre depot this morning, they changed it for a sticky weight with no fuss. Noise now stopped Many thanks! Matt.
