Thanks Rog and Ian 👍
It was buried deep in the parts manual. I was looking for steering, and missed it in suspension yesterday 🥴
Thought there was a bit of movement in the spherical joint when I gave the steering arm a pull yesterday, so I’ll start there and work inwards
Dave Hodgson, the MTWC scruitineer who picked up the fault seems keen to strip a rack down and sort out the problem. Will save it as a winter project ......
