My Roadster had a strange history. It came new with 'plastic' bushes and steering damper blades. The first owner had a big disagreement with the dealer and MMC about bump steer which he felt was dangerous. So early on the stubs were replaced with the later version , 06 onwards, with metal bushes.It doesn't look like the pins were changed. So at the second MOT with about 6k on the clock I got advisories on the pins. I changed them about a year later and both pins were badly worn. I don't know how well it had been greased leading up to that point.
I do believe though that there is little QC on the new pins & bushes and some are over reamed from new.
