General

These take braking loads (and accern loads syncro) and control the caster angle by virtue of the 
rear nut and cup washer on threaded rod.

When changing if you need to move the rear nut, then mark its position accurately first (controls caster angle)

When worn and corroded as bad as these parts, new ones make quite a difference to handling and surefootness of vehicle, esp. in roundabouts I found.
