visualising is a good tatic, it takes effort to fine tune this, but it can be incredibly powerful. “Watch your thoughts closely, as these may turn into actions” (Maggy Thatcher)

There are many things this could be. The most simple checks to make are:

Jack the car up one corner at a time, get a axle stand underneath so you don’t crush your self, and give the wheel a shake from left to right. Then again from top to bottom.

If this doesn’t create the same noise, then a good common area to look is the springs. Are any of them broken or cracked? the spring can still function and the car can still drive fine, but a broken section of spring may just be rattling in its position.

Failing this, you will need to get it on a ramp and have a good pull and a prod at all of the suspension arms and struts.

Let me know how you get on.
