When I bought my first Morgan from Allon White I was given a tip by Phil Benning. When hreasing kingpins lever up the bronze plate slightly and pump grease in until you see it come from the small gap you created. I did this regularly on less than 1k miles intervals quite often less than that on the 4/4 and later on the 2002 Plus8 and always before trips away. The Plus8 had hard chrome kingpins and no deterioration over 40k+ miles. I had a pneumatic grease gun so pry bar the plate and easy one handed greasegun triggering.
Rear leaf springs lubed with chain lube and Panhard rod ends ball/socket at the same time with spray grease.
