We have 2 Mogs used every day in all weathers and both have kingpins that lasted way longer than many expect.

I don't know if the parts of the USA where these cars live use salt on the road or not.

But I do wonder if the kingpin wear issue is due to lack of use?
The non hard chrome ones start to rust, then the rust wears away so wear rate is rapid.

So if used every day they don't get the surface corrosion that then wears of...

Just a thought
