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.

A broken radius rod
Andy Syncro-Nutz: The screw in type rods i have seen snapped right at the lower arm
fairwynds: I saw one (at a breakers yard!) that was bolted DIRECTLY to the sub frame! The subframe and bar were, to put it politely......s*&%ged! (not bushed with rubbers)
SAFETY: It seems likely that severe corrosion is responsible for thes breakages, so if you've any doubt, check them out. These rods act as drag-links for braking loads, they're very unlikely to ever break, but now at 20~25 years, looks like they can if water has been able to lodge between threads fro long enough, and at the front mount, it's an ideal water trap between sleeve, rod and rubber bushes.
The rubber bushes and sleeves should probably be disassembled and changed if corroded or worn anyway.
