The rear sub frame support pin that is.
One of mine has a strip of rust corrosion about 1mm deep right along the length of the shaft - not just surface but starting to eat below the surface. it's effecting the 'roundness' more than the strength integrity I would think but just wondering if it would be of concern.
This is the pin I mean
If you can imagine that strip of white as the rust that is about the size and shape
