Thanks Charlie,
I did that with my Series 1 but it was only a couple of small pits, because this is a continuous band of wear in the straight ahead position I'm going to look at the spare axle.
I'll keep the old ones and repair them with 'plastic metal' anyway, you never know when another project will come along.....
4-Wheel Drives used to get them ground down & re-chromed. Probably cheaper nowadays to import new parts depending on the shipping cost.
