But what is a proper quality one ?
The original types were.
No lapping needed, just take them form the box, shim, fit and grease. No lapping needed and nor should it be if they were quality joints.
<EDIT: There is no reference to lapping the ball joints in any of the factory manuals, because those joints didn't need lapping. They were finished at the point of manufacture.
My local friends are finding these days that when doing an Oil Change (5000 km / 3000 miles), the top ball joints also need replacing with what's currently available on the market. >
